Name of the Vulnerable Software and Affected Versions canonical-livepatch snap client versions prior to 10.15.0

Description Improper access control 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 issue is exploitable on systems where an administrator has enabled the Livepatch client with a valid Ubuntu Pro subscription. An attacker can use this token to access Livepatch services using the victim's credentials and potentially cause issues to the Livepatch server.

Recommendations Update canonical-livepatch snap client to version 10.15.0 or later.
