CVE-2025-37831

Local system crash via unchecked cpufreq result

Published May 8, 2025 · Updated May 11, 2026

NULL pointer dereference in the Apple SoC CPUFreq driver in Linux allows local users to crash the system via CPU frequency queries. When a query targets a CPU outside policy->cpus, apple_soc_cpufreq_get_rate() dereferences the NULL returned by cpufreq_cpu_get_raw(). Exploitation requires low-privileged local access, an Apple SoC using this driver, and the mismatched CPU policy state; the bounded consequence is a kernel crash.
