Linux Distros Unpatched Vulnerability : CVE-2026-14474

high Nessus Plugin ID 325413

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- A flaw was found in SSSD's LDAP sudo provider. When the ldap_sudo_search_base option is not explicitly configured, SSSD searches the entire LDAP directory tree for sudoRole objects. An authenticated attacker with write access to any subtree can inject a sudoRole object granting root-level sudo privileges on all SSSD-enrolled hosts. (CVE-2026-14474)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
