It provides an NSS and PAM interface toward the system and a pluggable back end system to connect to multiple different account sources. It is also the basis to provide client auditing and policy services for projects like FreeIPA.\r\n\r\nSecurity Fix(es):\n\nA flaw was found in sssd. When authenticating with a YubiKey, the SSSD PAM responder can crash due to a use-after-free vulnerability, where a memory pointer is incorrectly handled. A local attacker could exploit this flaw by manipulating smartcard or YubiKey contents, leading to a denial of service that disrupts authentication. This vulnerability also presents a potential for privilege escalation, although it is difficult to exploit.(CVE-2026-12610)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"sssd","purl":"pkg:rpm/openEuler/sssd&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.2-25.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["python2-sssd-2.2.2-25.oe2003sp4.aarch64.rpm","python3-sssd-2.2.2-25.oe2003sp4.aarch64.rpm","sssd-2.2.2-25.oe2003sp4.aarch64.rpm","sssd-debuginfo-2.2.2-25.oe2003sp4.aarch64.rpm","sssd-debugsource-2.2.2-25.oe2003sp4.aarch64.rpm","sssd-devel-2.2.2-25.oe2003sp4.aarch64.rpm"],"noarch":["sssd-help-2.2.2-25.oe2003sp4.noarch.rpm"],"src":["sssd-2.2.2-25.oe2003sp4.src.rpm"],"x86_64":["python2-sssd-2.2.2-25.oe2003sp4.x86_64.rpm","python3-sssd-2.2.2-25.oe2003sp4.x86_64.rpm","sssd-2.2.2-25.oe2003sp4.x86_64.rpm","sssd-debuginfo-2.2.2-25.oe2003sp4.x86_64.rpm","sssd-debugsource-2.2.2-25.oe2003sp4.x86_64.rpm","sssd-devel-2.2.2-25.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3022"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12610"}],"database_specific":{"severity":"Medium"}}
