CVE-2025-40194

A flaw was found in the Intel P-state driver (intel_pstate) in the Linux kernel. In the function update_qos_request(), a cpufreq_cpu_put() call happens too early, which is followed by freq_qos_update_request() that may still access the previously freed policy object. A race or object-lifecycle error on CPU hot removal (currently possible in virtualised environments) could lead to a crash (denial of service).
