NVD Description

Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by AlmaLinux.

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).
