In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: npc: Fix size of entry2cntr_map
KASAN prints below splat. This is caused by allocating counter for reserved mcam entry for cpt 2nd pass entry. But mcam->entry2cntr_map is not allocated for reserved entries.
BUG: KASAN: slab-out-of-bounds in npc_map_mcam_entry_and_cntr+0xb0/0x1a0 Write of size 2 at addr ffff0001033e7ffe by task kworker/0:1/14
