The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:97077 advisory.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: out-of-bounds read in the sssd (CVE-2026-6245)
* sssd: Use-after-free crash in SSSD' 'sssd_pam' process (CVE-2026-12610)
Bug Fix(es) and Enhancement(s):
* Concurrent child processes trigger unnecessarily backtrace (JIRA:RHEL-108116)
* Performance impact with enumerate in SSSD > 2.7.3 (JIRA:RHEL-109754)

* [RFE] SSSD PAM: Support Microsoft AD PKINIT authentication indicator (ms-pkca) for pam_gssapi_indicators_map (JIRA:RHEL-138905)
* Poor performance of `BE_REQ_INITGROUPS` handling by 'sssd_be' (LDAP RFC2307, no nested groups) (JIRA:RHEL-142964)
* SSSD needs to add Plasma Login Manager to the PAM services whitelist for the AD provider (JIRA:RHEL-154156)
* Detect foreign security principals in AD group members and silently ignore them (JIRA:RHEL-5049)

* [Regression] Cannot log in to FreeIPA account with password immediately after boot (JIRA:RHEL-173663)
* 'sssctl analyze --help' shows incorrect command in usage field (JIRA:RHEL-178180)
