CVE-2024-38573

In the Linux kernel, the following vulnerability has been resolved: cppc_cpufreq: Fix possible null pointer dereference cppc_cpufreq_get_rate() and hisi_cppc_cpufreq_get_rate() can be called from different places with various parameters. So cpufreq_cpu_get() can return null as 'policy' in some circumstances. Fix this bug by adding null return check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cppc_cpufreq: se corrige la posible desreferencia del puntero nulo. cppc_cpufreq_get_rate() y hisi_cppc_cpufreq_get_rate() se pueden llamar desde diferentes lugares con varios parámetros. Entonces cpufreq_cpu_get() puede devolver nulo como 'política' en algunas circunstancias. Corrija este error agregando una verificación de devolución nula.
