The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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.
