In the Linux kernel, the following vulnerability has been resolved: cpufreq: scmi: Fix null-ptr-deref in scmicpufreqgetrate() 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 cpufreqcpugetraw() to prevent this issue.
