Descriptions

McAfee Data Loss Prevention Endpoint (DLPe) before 9.3.400 allows local users to write to arbitrary memory locations, and consequently gain privileges, via a crafted (1) 0x00224014 or (2) 0x0022c018 IOCTL call.

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.
