Hi, The following vulnerability was published for sssd. CVE-2026-90463[0]: | A flaw was found in the sssd NSS responder. This input validation | vulnerability allows a local attacker, by sending specially crafted | service lookup requests to the NSS responder's UNIX socket, to cause | an out-of-bounds read. This out-of-bounds read may lead to a denial | of service (DoS) by crashing the NSS responder process. While | unprivileged local clients can typically reach the socket, there is | no evidence of privilege escalation or reliable data disclosure. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
