The Ubuntu security team deemed this advisory irrelevant for Ubuntu:25.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream keystone package and not the keystone package as distributed by Ubuntu.
A flaw was found in Keystone. There is a time lag (up to one hour in a default configuration) between when security policy says a token should be revoked from when it is actually revoked. This could allow a remote administrator to secretly maintain access for longer than expected.
