CVE-2022-50494

CVE-2022-50494 is concrete: in the Linux kernel, intel_powerclamp could crash when CPU 0 is offline due to using smp_processor_id() in preemptible code. The EulerOS advisories (EulerOS-SA-2026-1029/1172) explicitly include this CVE and describe the fix as replacing smp_processor_id() with get_cpu...
