In the Linux kernel, the following vulnerability has been resolved:
cpufreq: scmi: Fix null-ptr-deref in scmicpufreqget_rate()
cpufreqcpugetraw() can return NULL when the target CPU is not present in the policy->cpus mask. scmicpufreqgetrate() does not check for this case, which results in a NULL pointer dereference.
Add NULL check after cpufreqcpuget_raw() to prevent this issue.
