Vulnerability from fkie_nvd - Published: 2025-02-27 03:15 - Updated: 2025-11-03 21:19
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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).
