January Linux Patch Wednesday. Out of 424 total vulnerabilities, 271 are in the Linux Kernel. None show signs of exploitation in the wild, but 9 have public exploits.
🔸 RCE – Apache Tomcat (CVE-2024-56337). Based on the description, the vulnerability affects “case-insensitive file systems” like Windows or MacOS. However, Debian lists it as affecting tomcat9 and tomcat10. Either this is about rare case-insensitive Linux installations or there is an error in the description. 🤷♂️
🔸 RCE – Chromium (CVE-2025-0291). According to the FSTEC BDU, a public exploit exists.
🔸 RCE – 7-Zip (CVE-2024-11477). What’s in the public is not an exploit, but a write-up.
🔸 Memory Corruption – Theora (CVE-2024-56431). It’s not clear yet how to exploit this. 🤷♂️
