Incorrect Conversion between Numeric Types Affecting perf package, versions *
Threat Intelligence
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.

binfmt_misc: fix shift-out-of-bounds in check_special_flags
UBSAN reported a shift-out-of-bounds warning:
