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:
vp_vdpa: fix the crash in hot unplug with vp_vdpa
While unplugging the vp_vdpa device, it triggers a kernel panic The root cause is: vdpa_mgmtdev_unregister() will accesses modern devices which will cause a use after free. So need to change the sequence in vp_vdpa_remove
