CVSS 7.8 · High EPSS 0,10%
Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') pada linux kernel. Skor CVSS 3.1 7.8 (High) menurut CNA.
In the Linux kernel, the following vulnerability has been resolved: perf: Fix __perf_event_overflow() vs perf_remove_from_context() race Make sure that __perf_event_overflow() runs with IRQs disabled for all possible callchains. Specifically the software events can end up running it with only preemption disabled. This opens up a race vs perf_event_exit_event() and friends that will go and free various things the overflow path expects to be present, like the BPF program.
