| Doc Text: |
A reference leak flaw was found in the Linux kernel's AMD P-state unit test driver in the CPU policy access logic. A local user can trigger this issue by loading the amd-pstate-ut driver, which acquires CPU policy references via cpufreq_cpu_get without releasing them via cpufreq_cpu_put. This causes other processes attempting to access the policy to block indefinitely, resulting in hung tasks and denial of service through system unresponsiveness.
