Summary
arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array
Details

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).
