CVE-2026-98132

The Linux kernel bpf verifier contains a flaw in states.c:__clean_func_state() where it can incorrectly downgrade half-dead scalar zero spills to STACK_ZERO. Specifically, when 4 bytes of a 64-bit spill are dead, the verifier changes the spill to a combination of zero and poison values (0000pppp)...
