CVE-2024-53230

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

cpufreq: CPPC: Fix possible null-ptr-deref for cppc_get_cpu_cost()

cpufreq_cpu_get_raw() may return NULL if the cpu is not in policy->cpus cpu mask and it will cause null pointer dereference, so check NULL for cppc_get_cpu_cost().
