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:
netfilter: nft_set_rbtree: check for partial overlaps in anonymous sets
Userspace provides an optimized representation in case intervals are adjacent, where the end element is omitted.
The existing partial overlap detection logic skips anonymous set checks on start elements for this reason.
However, it is possible to add intervals that overlap to this anonymous where two start elements with the same, eg. A-B, A-C where C < B.
start end
A B
start end
A C
Restore the check on overlapping start elements to report an overlap.
