Elevation of Privilege (Local Privilege Escalation) – Linux Kernel (CVE-2024-1086) has been added to CISA KEV. The vulnerability itself is relatively old, from January. I already wrote about it in March, when the write-up and public exploit were released.
Despite the fact that the exploitation of this vulnerability is trivial (the attacker launches a local utility and gains root privileges), until recently there were no signs of exploitation in the wild. This is quite strange: such a useful exploit should immediately be included in the attackers’ toolkit. So either the practical exploitation of this vulnerability is somehow complicated, or the attackers did not leave any traces. 🤔
In any case, on May 30, the vulnerability was added to CISA KEV, and this means the fact of its exploitation in attacks has been proven. But there are no details yet. Please be aware of this vulnerability when upgrading Linux hosts.
