Linux: Out-of-bounds Read
CVE-2025-22118 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 4161cf3f4c11006507f4e02bedc048a215a4b81a, e2f7d3f7331b92cb820da23e8c45133305da1e63 as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.18% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to 4161cf3f4c11006507f4e02bedc048a215a4b81a or e2f7d3f7331b92cb820da23e8c45133305da1e63, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.14.2 or a later version.
