CVE-2026-73281  (opens in a new tab)
CWE-669  (opens in a new tab)

How to fix?

Upgrade Ubuntu:22.04 openssh to version 1:8.9p1-3ubuntu0.17 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.
