RHSA-2026:49841 - Important: sssd security update

Synopsis

Important: sssd security update

Type/Severity

Security Advisory: Important

Topic

An update for sssd is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

The System Security Services Daemon (SSSD) service provides a set of daemons to manage access to remote directories and authentication mechanisms. It also provides the Name Service Switch (NSS) and the Pluggable Authentication Modules (PAM) interfaces toward the system, and a pluggable back-end system to connect to multiple different account sources.

Security Fix(es):

sssd: sssd: sudo LDAP provider searches entire directory tree for sudoRole objects by default, enabling privilege escalation (CVE-2026-14474)
sssd: sssd: GPO cache path traversal via unsanitized gPCFileSysPath allows Kerberos authentication bypass (CVE-2026-14476)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
