Score 7.8 from GitHub Security Advisory (severity: HIGH) published 2025-02-27. NVD baseline CVSS 7.8; sources differ by 0.0.
A fix is available — apply it.
In the Linux kernel, the following vulnerability has been resolved:
arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array
The loop that detects/populates cache information already has a bounds check on the array size but does not account for cache levels with separate data/instructions cache. Fix this by incrementing the index for any populated leaf (instead of any populated level).
EG Risk is EchelonGraph's 0–100 priority score: it fuses intrinsic severity with real-world exploitation and automatability so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner. Distinct from the 0–10 EG Score (severity).
