In the Linux kernel, the following vulnerability has been resolved:

perf/x86/amd: Check event before enable to avoid GPF

On AMD machines cpuc->events[idx] can become NULL in a subtle race condition with NMI->throttle->x86_pmu_stop().

Check event for NULL in amd_pmu_enable_all() before enable to avoid a GPF. This appears to be an AMD only issue.

Syzkaller reported a GPF in amd_pmu_enable_all.
