Linux: Out-of-bounds Read
CVE-2025-38599 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 f82eabd0ff8067d1ee95515f4174c9a9569d54cb, f43e7d8ae4b6a73213032545552bab26f76f113a, 64cbf0d7ce9afe20666da90ec6ecaec6ba5ac64b 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 0.23% 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 f82eabd0ff8067d1ee95515f4174c9a9569d54cb or f43e7d8ae4b6a73213032545552bab26f76f113a or 64cbf0d7ce9afe20666da90ec6ecaec6ba5ac64b, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.15.10 or 6.16.1, whichever matches your release line, or a later version.

How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- LowA basic user account is enough.
- User interaction
- NoneNo action by a victim is required.
