Title
arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array
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).
Severity
7.8 (High)
