August Linux Patch Wednesday

August Linux Patch Wednesday

August Linux Patch Wednesday. A total of 3,060 vulnerabilities. For comparison, there were 2,017 in July. That's a 52% increase and another new record. This time, there are 1,354 vulnerabilities in the Linux Kernel and 447 in Chromium. For 3 vulnerabilities, there are signs of exploitation in the wild:

🔻 RCE - Jenkins (CVE-2026-53435). Jenkins is a development automation server used to build, test, and deploy software. The vulnerability allows a remote authenticated attacker to use the Script Console to execute arbitrary code and read files from the Jenkins controller. The vulnerability was added to the VulnCheck KEV on June 15 and fixed in RedOS on August 12.

🔻 CodeInj - WordPress (CVE-2026-60137). WordPress is a popular open-source CMS for creating websites and blogs. The vulnerability leads to a blind SQL injection in the WordPress core, allowing a remote unauthenticated attacker to read user accounts and password hashes from the WordPress database. Code execution is then possible by installing a malicious plugin. Multiple public exploits are available. The vulnerability was added to the CISA KEV catalog on July 21. A fix for the wordpress package in the Debian repository was released on July 23.

🔻 RCE - SPIP (CVE-2026-77647). SPIP is an open-source CMS for creating and collaboratively editing websites. The vulnerability allows an unauthenticated remote attacker to execute arbitrary PHP code. The vulnerability was added to the VulnCheck KEV on August 20. A fix for the spip package in the Debian repository was released on August 18.

Strictly speaking, the report contains one more vulnerability RCE - WinRAR (CVE-2025-8088) that is being exploited in the wild. The vulnerability was fixed in the clamav package in the Alt Linux repository. However, exploitation is only possible on Windows, so it is out of scope.

Another 127 vulnerabilities are not known to be exploited in the wild, but public exploits are available for them, or there are indications that such exploits exist. Notable examples include:

🔸 RCE - Action Pack "KindaRails2Shell" (CVE-2026-66066). Action Pack is a component of Ruby on Rails responsible for handling web requests, routing, and generating responses. An attacker can upload a specially crafted image to a vulnerable application and achieve remote code execution.

🔸 RCE - WordPress "XSS2Shell" (CVE-2026-64638). The attack chain allows an unauthenticated XSS on the login page to be escalated to arbitrary PHP code execution.

🔸 CodeInj - PHP (CVE-2026-17543). Improper escaping of backslashes in attacker-controlled parameters can lead to a trivial SQL injection in PHP.

🔸 EoP - Linux Kernel "Zapscape" (CVE-2026-64561). This KVM escape vulnerability allows an attacker to break out of a virtual machine in KVM/x86 environments and execute commands on the host with root privileges.

🔸 EoP - Linux Kernel "OVSwrap" (CVE-2026-64531), Linux Kernel "SCTPhantom" (CVE-2026-64564), Linux Kernel "Ubuntu PPPoL2TP" (CVE-2026-68398). These vulnerabilities allow a local attacker to escalate privileges to root.

🔸 AuthBypass - Traefik (CVE-2026-48020). Traefik is an HTTP reverse proxy and load balancer. A high-severity vulnerability in the StripPrefix middleware allows an unauthenticated attacker to bypass route-level authentication and authorization.

August Microsoft Patch Tuesday

August Microsoft Patch Tuesday

August Microsoft Patch Tuesday. A total of 401 vulnerabilities were addressed - 170 fewer than in July. One of the vulnerabilities is known to be actively exploited in the wild:

🔻 EoP - Windows Ancillary Function Driver for WinSock (CVE-2026-68820). A local attacker can exploit this vulnerability to gain SYSTEM-level privileges. There is a contradiction in Microsoft's description: the Exploit Code Maturity in CVSS is marked as "Unproven", while at the same time Microsoft states that the vulnerability is being exploited in the wild. 🤷‍♂️

Public exploits are available for two other vulnerabilities:

🔸 EoP - Windows User Profile Service (CVE-2026-62832). This vulnerability allows an authenticated attacker to elevate privileges to ADMINISTRATOR level. Rapid7 believes this vulnerability is related to the LegacyHive exploit, which was published on July 14.

🔸 EoP - Windows Kernel (CVE-2026-62737). This vulnerability allows an authenticated attacker to elevate privileges to SYSTEM level. An exploit has been publicly available since August 11.

Among the remaining vulnerabilities, the following stand out:

🔹 RCE - Windows DNS Server (CVE-2026-62878). This wormable vulnerability allows a remote unauthenticated attacker to execute code on a vulnerable server with elevated privileges. It is recommended to test and install the update as soon as possible, especially on Internet-facing DNS servers.

🔹 RCE - Windows Deployment Services TFTP Server (CVE-2026-62893). This vulnerability, discovered as part of the ZDI (Zero Day Initiative) program, allows an attacker to execute code without authentication or user interaction. TFTP has no authentication mechanism and is available remotely via UDP port 69. Any WDS server serving Windows Imaging Format (WIM) files via TFTP, which is the standard PXE boot scenario, is vulnerable. The issue results from the lack of validation of the existence of an object before performing operations on it. UDP port 69 should be blocked at the perimeter, but attackers could easily use this vulnerability for lateral movement within an organization. If you're using WDS for deployments, test and install this update quickly.

🔹 RCE - Windows DHCP Server (CVE-2026-62823). Successful exploitation of this vulnerability allows a remote unauthenticated attacker to execute arbitrary code from an adjacent network by sending a specially crafted packet that triggers a heap-based buffer overflow.

🔹 EoP - Microsoft Exchange (CVE-2026-62911). This vulnerability allows a remote authenticated attacker (with Privileges Required: Low according to CVSS) to gain control over the mailboxes of all Exchange users, send and read emails, and download attachments. This vulnerability was demonstrated at Pwn2Own Berlin. ZDI researchers provided Microsoft with working exploits.

🔹 RCE - Microsoft QUIC (CVE-2026-62815). This use-after-free vulnerability allows an unauthenticated attacker to execute arbitrary code on a target system by sending a specially crafted network packet. QUIC is an IETF-standardized transport protocol that runs over UDP instead of TCP and serves as the foundation for HTTP/3. The protocol is used by approximately 13.5 million websites.

🔹 Tampering - Windows Container Isolation FS Filter Driver (unionfs.sys) (CVE-2026-72971). This vulnerability reportedly allows an attacker to overwrite certain files. As a result, an attacker could perform an action within a container that could impact the host system.

July Linux Patch Wednesday

July Linux Patch Wednesday

July Linux Patch Wednesday. A total of 2,017 vulnerabilities were addressed (539 in the Linux kernel and 504 in Chromium). For comparison, there were 1,888 vulnerabilities in June. Once again, a new record. Moreover, next month will most likely set another record, as 1,704 vulnerabilities have already been addressed 2.5 weeks before the August LPW. 🤷‍♂️ But for now, let's take a closer look at the July report. Only one vulnerability shows signs of exploitation in the wild:

🔻 RCE - Gogs (CVE-2025-8110). Gogs is a self-hosted web service for managing Git repositories, similar in purpose to GitHub or GitLab. An attacker can achieve remote code execution by manipulating the .git/config file through symbolic link bypasses and injecting commands via sshCommand. Multiple public exploits are available on GitHub. The vulnerability has been added to the CISA KEV catalog.

There are also 178 vulnerabilities with public exploits available or indications that they exist, but there are currently no signs of exploitation in the wild. For comparison, last month there were 109 such vulnerabilities. Among them, the following stand out:

🔸 RCE - NGINX (CVE-2026-42533). NGINX is a web server and software for handling network requests, which is often used as a reverse proxy, load balancer, and gateway for web applications. An unauthenticated attacker can exploit this vulnerability for remote code execution by sending crafted HTTP requests.

🔸 RCE - libssh2 (CVE-2026-55200). libssh2 is a C library that implements the SSH-2 protocol and allows applications to establish secure SSH connections, execute commands, and transfer files via SFTP/SCP. A remote attacker can send crafted SSH packets with excessively large packet_length values to corrupt heap memory and achieve remote code execution.

🔸 RCE - Linux Kernel "RefluXFS" (CVE-2026-64600). An attacker with an ordinary local account can exploit the vulnerability to overwrite protected files on disk and gain root privileges on affected systems, including installations running SELinux in Enforcing mode. In practice, the vulnerability allows an attacker to set an empty root password.

🔸 RCE - Gogs (CVE-2025-64111). Due to an insufficient patch for CVE-2024-56731, it is still possible to modify files in the .git directory and achieve remote command execution. Based on the exploit code, authentication is required for exploitation.

🔸 CodeInj - MediaWiki (CVE-2026-58025). MediaWiki is a free and open-source web platform for creating and managing wiki websites, powering Wikipedia and other collaborative content editing projects. An attacker with the importupload or import permission (default: sysop group) can craft a malicious XML import file containing serialized PHP objects in params fields, triggering arbitrary object instantiation and potentially leading to remote code execution through gadget chains.

🔸 RCE - FFmpeg (CVE-2026-8461). FFmpeg is a free and open-source collection of libraries and utilities for processing audio and video data. An out-of-bounds write vulnerability in FFmpeg's libavcodec library, specifically in the MagicYUV decoder, allows denial-of-service and, in some cases, can be exploited for remote code execution.

🔸 RCE - 7-Zip (CVE-2026-14266). 7-Zip is a free and open-source file archiver that allows users to create and extract archives in various formats, including its native 7z format, ZIP, RAR, and others. Crafted XZ-compressed data can trigger an overflow of a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

🔸 MemCor - Linux Kernel (CVE-2026-53359). This is essentially a KVM vulnerability. KVM (Kernel-based Virtual Machine) is a virtualization technology built into the Linux kernel that allows multiple isolated virtual machines to run on a single physical server. A KVM escape vulnerability lets a guest escape to the host in a KVM/x86 environment. It is triggerable on both Intel and AMD.

July Microsoft Patch Tuesday

July Microsoft Patch Tuesday

July Microsoft Patch Tuesday. In the second week of July, I was on vacation in St. Petersburg. After that, I got caught up with a bunch of other tasks, so I'm only publishing this roundup now. Better late than never, especially considering how unusual this MSPT turned out to be. 😉 In total, 571 vulnerabilities were addressed - almost three times (❗️) more than in June. There are four vulnerabilities that have been reported as exploited in the wild:

🔻 RCE - Microsoft SharePoint (CVE-2026-58644). An attacker with Site Owner privileges or higher can remotely inject and execute arbitrary code on the SharePoint Server.

🔻 RCE - Microsoft SharePoint (CVE-2026-50522). The vulnerability description is identical to CVE-2026-58644. According to ZDI, the CVE-2026-50522 vulnerability was successfully demonstrated at Pwn2Own Berlin. Despite this, Microsoft rates its Exploit Maturity as "Unknown", even though researchers have already provided a working exploit to the company. This once again shows that organizations should not rely solely on software vendors' assessments and should instead perform their own risk evaluation. If you have Internet-facing SharePoint servers, you should test and deploy the patch addressing this vulnerability as soon as possible.

🔻 EoP - Microsoft SharePoint Server (CVE-2026-56164). Missing authentication for a critical function in Microsoft Office SharePoint could allow an unauthenticated attacker to elevate privileges over a network. Microsoft mentioned in the advisory that enabling the Antimalware Scan Interface (AMSI) on the server and setting the Request Body Scan mode to Full can help mitigate this flaw.

🔻 EoP - Active Directory Federation Services (CVE-2026-56155). Insufficient granularity of access control (CWE-1220) in Active Directory Federation Services (AD FS) allows an authorized attacker to elevate privileges locally. An attacker who successfully exploited this vulnerability could gain administrator privileges.

There are eight more vulnerabilities with publicly available exploits:

🔸 EoP - Windows User Interface Core (CVE-2026-50454). Relative path traversal (CWE-23) allows an authorized attacker to elevate privileges locally. An attacker who successfully exploited this vulnerability could gain SYSTEM privileges. The PoC starts from a normal, non-elevated process belonging to a local administrator and opens an interactive command prompt as NT AUTHORITY\SYSTEM.

🔸 EoP - Windows WalletService (CVE-2026-49176). Improper privilege management (CWE-269) allows an authorized attacker to elevate privileges locally. The exploit PoC starts a command prompt as SYSTEM in the active desktop session.

🔸 RCE - Microsoft Message Queuing Queue Manager (CVE-2026-54992). The existing exploit PoC demonstrates denial of service; it does not demonstrate code execution.

🔸 EoP - Windows Narrator Braille (CVE-2026-58635). According to Microsoft's description, an attacker who successfully exploited this vulnerability could execute code in the security context of the NT AUTHORITY\Network Service account. However, the description of the exploit PoC states that an unprivileged attacker would gain NT AUTHORITY\SYSTEM privileges.

🔸 EoP - Windows Cloud Files Mini Filter Driver (CVE-2026-58613). Use after free (CWE-416) in the Windows Cloud Files Mini Filter Driver allows an authorized attacker to elevate privileges locally. An attacker who successfully exploits this vulnerability can gain SYSTEM privileges. Exploitation details are available in the Talos Vulnerability Report TALOS-2026-2426.

🔸 InfDisc - Windows Win32k (CVE-2026-50416). An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory. The exploit PoC description mentions Chrome tabs, Discord, Explorer, Spotify, and tray windows. However, it seems that it will not be possible to intercept passwords using this vulnerability.

🔸 InfDisc - Windows Kernel (CVE-2026-50475). A buffer over-read (CWE-126) in the Windows Kernel allows an authorized attacker to disclose information locally. Exploitation details are available in the Talos Vulnerability Report TALOS-2026-2443.

🔸 EoP - Azure Spring Apps (CVE-2026-50338). An attacker who successfully exploited this vulnerability could gain elevated privileges, potentially allowing them to perform actions beyond their original permissions. According to the author of the exploit PoC, the vulnerability is a Spring Cloud Azure B2C resource server cross-issuer authentication bypass.

Among the remaining vulnerabilities, the following can be highlighted:

🔹 RCE - Windows Remote Desktop Protocol (CVE-2026-56190). An unauthenticated, network-reachable, no user interaction required vulnerability. The root cause is a classic one: the use of an uninitialized resource (CWE-908), meaning specially crafted RDP traffic can interact with memory that was never properly initialized, letting an attacker corrupt memory and potentially steer code execution. RDP Servers are a common target, so audit your systems to see which are internet accessible and start from there.

🔹 RCE - Microsoft Dynamics NAV and Microsoft Dynamics 365 Business Central (On Premises) (CVE-2026-55944). Successful exploitation can be achieved by sending a crafted login request to an affected Dynamics NAV or Business Central server in order to trigger a deserialization of untrusted data vulnerability. Microsoft's advisory cautions that no user-interaction is required, nor is authentication a requirement in order to successfully exploit this vulnerability.

🔹 EoP - Microsoft Windows VMSwitch (CVE-2026-57092). It's a use-after-free that lets a low-privileged attacker escalate to full host compromise across a VM boundary. ZDI reported that a similar exploit was demonstrated on ESXi at Pwn2Own Berlin, but this issue is not limited to ESXi. If you use VMSwitch in Hyper-V deployments (which is likely), test and deploy the fix quickly.

🔹 Spoofing - Microsoft Exchange (CVE-2026-55008). An attacker can send a specially crafted email that runs arbitrary JavaScript when the victim opens it in OWA. No attachment or macro is required - simply viewing the email is enough. If your organization uses OWA, it is recommended to test and deploy the fix as soon as possible.

🔹 RCE - Windows DHCP Server (CVE-2026-50518, CVE-2026-56159, CVE-2026-48564, CVE-2026-50370), Windows DHCP Client (CVE-2026-54128), Windows Message Queuing Service (MSMQ) (CVE-2026-50447), Windows Admin Center (WAC) (CVE-2026-56196), Windows FTP Service (CVE-2026-49172), Windows GDI+ (CVE-2026-50380), Windows Server Network driver (CVE-2026-56188), Microsoft Exchange (CVE-2026-55005), Windows Active Directory Domain Services (CVE-2026-49178), Windows Remote Desktop Client (CVE-2026-50474), Windows Remote Desktop Client (CVE-2026-54990, CVE-2026-58594), Windows TCP/IP (CVE-2026-54999), Windows Print Spooler (CVE-2026-58608), Windows Reliable Multicast Transport Driver (RMCAST) (CVE-2026-54982, CVE-2026-54995), Microsoft SQL Server (CVE-2026-54117), Microsoft Copilot (CVE-2026-48561).

🔹 SFB - Microsoft SharePoint Server (CVE-2026-55040).

🔹 EoP - Windows Server Update Service (WSUS) (CVE-2026-50444), Active Directory Certificate Services (CVE-2026-54121).

There is also a rather curious vulnerability:

RCE - Game: Age of Empires II: Definitive Edition (CVE-2026-50663). 😃 A relative path traversal in Age of Empires II: Definitive Edition Game allows an unauthorized attacker to execute code over a network. Age of Empires II is a cult classic real-time strategy game by Microsoft, set in the medieval era. Players develop chosen civilizations, manage resources, research technologies, and command armies in historical campaigns and multiplayer battles. The Definitive Edition features improved graphics, updated audio, and additional content. If you're still playing this game, be sure to update. 😉

June Microsoft Patch Tuesday

June Microsoft Patch Tuesday

June Microsoft Patch Tuesday. Last week I was on vacation in Veliky Novgorod, so I'm publishing this overview only now. A total of 202 vulnerabilities were addressed, approximately twice as many as in May. There are currently no vulnerabilities marked as exploited in the wild. However, there are two vulnerabilities with publicly available exploits:

🔸 RCE - HTTP.sys (CVE-2026-47291). This critical vulnerability allows remote, unauthenticated attackers to execute arbitrary code on affected systems without user interaction. However, systems using the default MaxRequestBytes registry value in the Windows HTTP stack are not affected. If needed, you can change this registry setting to protect systems while testing and deploying the patch. Microsoft's security bulletin includes instructions and a PowerShell script for this workaround.

🔸 DoS - HTTP.sys (CVE-2026-49160). The same exploit is used as for the previous RCE vulnerability.

It is also worth paying attention to vulnerabilities that Microsoft has flagged as having a publicly available exploit:

🔹 SFB - Windows BitLocker (CVE-2026-50507). A successful attacker could bypass the BitLocker Device Encryption feature on the system storage device. An attacker with physical access to the target could exploit this vulnerability to gain access to encrypted data. According to Tenable, this is the "Bitskrieg" vulnerability discovered by the researcher known as Chaotic Eclipse/Nightmare Eclipse.

🔹 SFB - Secure Boot (CVE-2026-48570). An attacker who successfully exploited this vulnerability could bypass Secure Boot. This vulnerability was reported by Alon Leviev (STORM), who is known for previous research related to BootKitty and BlackLotus.

Among the remaining vulnerabilities, the following are worth highlighting:

🔹 RCE - Windows Kernel (CVE-2026-45657). This vulnerability allows remote, unauthenticated attackers to run code with SYSTEM privileges without any user interaction. In other words, it could be used to spread automatically between systems. The issue is caused by how the Windows kernel processes TCP/IP traffic. Microsoft rated this as "Exploitation Less Likely", but security researchers and exploit developers are already analyzing the patch and trying to build an exploit. Test and deploy this patch as soon as possible.

🔹 EoP - Windows Collaborative Translation Framework (CTFMON) (CVE-2026-45586). This vulnerability affects a component used for voice and handwriting recognition. If exploited, an attacker could gain SYSTEM privileges. Microsoft rates this vulnerability as "Exploitation More Likely".

🔹 RCE - Windows Remote Desktop Client (CVE-2026-42909, CVE-2026-42913, CVE-2026-42985, CVE-2026-42992, CVE-2026-42993, CVE-2026-44799, CVE-2026-44801, CVE-2026-47289, CVE-2026-47653, CVE-2026-47654, CVE-2026-48563). Successful exploitation would require a victim to connect to an attacker-controlled server using an affected version of the Remote Desktop Client. This action could trigger a heap-based buffer overflow, resulting in remote code execution.

🔹 RCE - DHCP Client Service (CVE-2026-44815). This vulnerability allows remote, unauthenticated attackers to execute code on affected systems without user interaction. Because the DHCP client is widely enabled across Windows systems, this vulnerability presents a broad attack surface. Organizations should prioritize testing and deploying the patch for this vulnerability as soon as possible.
