CVE-2026-98061

The Linux kernel contains a vulnerability in the BPF verifier where tail calls made directly from synchronous callback frames trigger a verifier bug. The root cause is that prepare_func_exit() marks register R0 as precise for callbacks, but the tail-call path synthesizes R0 instead of deriving it...
