CVE-2026-80626

A flaw was found in the Linux kernel's powerpc/perf component. An issue in the fslembpmudel function can lead to a preempt count underflow. This occurs when the function attempts to decrement a preemption counter without a corresponding increment, specifically when event-hw.idx is negative. On...
