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.
