CVE-2026-6369 | BDVDB-2026-327707 Detail

Canonicalcanonical-livepatch

Description#

An improper access control vulnerability in the canonical-livepatch snap client prior to version 10.15.0 allows a local unprivileged user to obtain a sensitive, root-level authentication token by sending an unauthenticated request to the livepatchd.sock Unix domain socket. This vulnerability is exploitable on systems where an administrator has already enabled the Livepatch client with a valid Ubuntu Pro subscription. This token allows an attacker to access Livepatch services using the victim's credentials, as well as potentially cause issues to the Livepatch server.
