CVE-2025-38038: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: cpufreq: amd-pstate: Remove unnecessary driver_lock in set_boost set_boost is a per-policy function call, hence a driver wide lock is unnecessary. Also this mutex_acquire can collide with the mutex_acquire from the mode-switch path in status_store(), which can lead to a deadlock. So, remove it.

Affected products

• Linux Linux Kernel: from 5.17, before 6.12.31 (fixed in 6.12.31); from 6.13, before 6.14.9 (fixed in 6.14.9)
