SB2025112586 - SUSE update for sssd

Description

This security bulletin contains information about 1 security vulnerability.

1) Improper privilege management (CVE-ID: CVE-2025-11561)

The vulnerability allows a remote user to bypass authorization checks.

The vulnerability exists due to improper privilege management within the Active Directory integration feature. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.

Remediation

Install update from vendor's website.
