原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
A flaw was found in SSSD. An unprivileged local user can repeatedly request master automount map updates through the autofs responder due to missing authorization checks. This triggers global cache invalidation and forces repeated lookups to backend directory providers, leading to a Denial of Service (DoS) from degraded automount availability and elevated resource consumption.
