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...
