CVE-2026-80669

In the Linux kernel, the following vulnerability has been resolved:

bpf: Disable xfrm_decode_session hook attachment

BPF LSM programs can currently attach to xfrm_decode_session(). That

hook may return an error, but security_skb_classify_flow() calls it

from a void path and triggers BUG_ON() if an error is returned.

Disable BPF attachment to the hook to prevent a BPF LSM program from

turning packet classification into a full panic.
