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.
