Description
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.
