CVE-2026-68742

Name of the Vulnerable Software and Affected Versions SSSD (affected versions not specified)

Description A flaw exists in the NSS responder where the sss nss protocol parse addr() function fails to validate the addrlen field against the remaining packet body size. A local attacker can exploit this by sending a crafted GETHOSTBYADDR request to the NSS responder socket, leading to an out-of-bounds read and a process crash, which results in a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
