CVE-2026-98132
A flaw exists in the Linux kernel 's Berkeley Packet Filter (BPF) verifier, specifically within the states.c:__clean_func_state() function. The vulnerability occurs when the verifier incorrectly downgrades a half-dead scalar zero spill to STACK_ZERO because a portion of the stack memory is consid...
