CVE-2026-14476: Red Hat Enterprise Linux 10

High severity, CVSS 8.0. EPSS: 0.7% chance of exploitation in the next 30 days.

A path traversal flaw was found in SSSD's AD GPO provider. The ad_gpo_extract_smb_components() function does not sanitize .. sequences in the gPCFileSysPath LDAP attribute, allowing an attacker with AD GPO management access to write files outside the GPO cache directory as root. On default RHEL configurations with SELinux enforcing, this can be used to inject Kerberos configuration leading to authentication bypass.
