Amazon Linux 2 Security Advisory: ALAS2-2025-3050
Advisory Released Date: 2025-10-27
Advisory Updated Date: 2025-10-27
Severity:
Important
Issue Overview:
A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, SSSD does not enable the Kerberos local authentication plugin (sssd_krb5_localauth_plugin), allowing an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users. This can result in unauthorized access or privilege escalation on domain-joined Linux hosts. (CVE-2025-11561)
Affected Packages:
sssd
Note:
This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.
Issue Correction:
Run yum update sssd or yum update --advisory ALAS2-2025-3050 to update your system.
