The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: Stop the active perfmon before being destroyed
Upon closing the file descriptor, the active performance monitor is not
stopped. Although all perfmons are destroyed in vc4_perfmon_close_file()
,
the active performance monitor's pointer (vc4->active_perfmon
) is still
retained.
If we open a new file descriptor and submit a few jobs with performance
monitors, the driver will attempt to stop the active performance monitor
using the stale pointer in vc4->active_perfmon
. However, this pointer
is no longer valid because the previous process has already terminated,
and all performance monitors associated with it have been destroyed and
freed.
To fix this, when the active performance monitor belongs to a given process, explicitly stop it before destroying and freeing it.
