CVE-2025-39821

CVE-2025-39821 (Linux kernel perf - UBSAN risk) The issue is a logic flaw in perf event throttling where a group’s disabled member in PERF_EVENT_STATE_OFF could be throttle-started/stoppped, causing PMU drivers to receive an event with hw.idx = -1. This negative index is used as a shift exponent ...
