CVE-2026-43453

CVE-2026-43453 is a Linux kernel issue in the netfilter nft_set_pipapo path. The bug is a stack out-of-bounds read in pipapo_drop(), where rulemap[i+1].n is passed to pipapo_unmap() on every iteration, including the last when i == m->field_count-1. This reads past the end of the stack-allocate...
