EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/1372/info A denial of service attack exists in the NFS lock daemon supplied with Linux. By connecting to the port rpc.lockd is running on, and supplying random input, it will cause lockd to exit with an error. The socket associated with rpc.lockd is also not properly released, and cannot be rebound to without a reboot. This vulnerability most likely affects all Linux distributions running NFS.
