CVE-2025-37830 Information

Description

In the Linux kernel the following vulnerability has been resolved:

cpufreq: scmi: Fix null-ptr-deref in scmi_cpufreq_get_rate()

cpufreq_cpu_get_raw() can return NULL when the target CPU is not present in the policy->cpus mask. scmi_cpufreq_get_rate() does not check for this case which results in a NULL pointer dereference.

Add NULL check after cpufreq_cpu_get_raw() to prevent this issue.
