Description SMASH SMASH 2024-05-22 16:26:04 UTC 
In the Linux kernel, the following vulnerability has been resolved:

cpufreq: CPPC: Fix potential memleak in cppc_cpufreq_cpu_init

It's a classic example of memleak, we allocate something, we fail and
never free the resources.

Make sure we free all resources on policy ->init() failures.
