CVE-2024-38573
Linux kernel CPPC_Cpufreq Null Pointer Dereference Navigator Vulnerability
Description
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.
