CVE-2026-72325

A flaw was found in the Linux kernel's performance monitoring unit PMU for AMD processors. When Secure Virtual Machine SVM is toggled on a CPU with active Last Branch Record LBR events, the system incorrectly attempts to enable Branch Sampling BRS on hardware that does not support it. This...

CVE-2026-72325

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/core: Avoid enabling BRS from the SVM reload path Branch Sampling BRS and Last Branch Record LBR are mutually exclusive hardware features, and users of both are tracked via cpuc-lbrusers. When SVM is toggled on a CPU...

CVE-2025-68798

A race condition flaw was found in the Linux kernel's AMD performance monitoring unit PMU code. A subtle timing window exists between NMI-triggered throttling which clears an event pointer and amdpmuenableall which dereferences it. This can result in a NULL pointer dereference and kernel crash on...
