CVE-2026-23435

In the Linux kernel, the following vulnerability has been resolved: perf/x86: Move event pointer setup earlier in x86pmuenable A production AMD EPYC system crashed with a NULL pointer dereference in the PMU NMI handler: BUG: kernel NULL pointer dereference, address: 0000000000000198 RIP:...

CVE-2026-23435

The CVE-2026-23435 entries describe a Linux kernel PMU/X86 perf vulnerability that was resolved. The root cause was a commit that moved cpuc->events[idx] assignment out of x86_pmu_start() into step 2 of x86_pmu_enable(), after PERF_HES_ARCH checks. This could allow a path that calls pmu->st...

CVE-2025-68798

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: Check event before enable to avoid GPF On AMD machines cpuc-eventsidx can become NULL in a subtle race condition with NMI-throttle-x86pmustop. Check event for NULL in amdpmuenableall before enable to avoid a GPF. Th...

CVE-2022-49781
