Description OSIDB Bzimport 2025-03-07 10:01:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

cpufreq/amd-pstate: Fix cpufreq_policy ref counting

amd_pstate_update_limits() takes a cpufreq_policy reference but doesn't
decrement the refcount in one of the exit paths, fix that.
