CVE-2026-80669

Published Aug 28, 2026

Overview

CVE-2026-80669 is a known-severity vulnerability. It was published on August 28, 2026.

Technical Description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
