NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-devel-matched package and not the kernel-64k-debug-devel-matched package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
regmap: maple: Fix cache corruption in regcache_maple_drop()
When keeping the upper end of a cache block entry, the entry[] array must be indexed by the offset from the base register of the block, i.e. max - mas.index.
The code was indexing entry[] by only the register address, leading to an out-of-bounds access that copied some part of the kernel memory over the cache contents.
This bug was not detected by the regmap KUnit test because it only tests with a block of registers starting at 0, so mas.index == 0.
