Red Hat Enterprise Linux: null pointer dereference
Medium6.5CVE-2026-73199 · Published Aug 20, 2026
A flaw was found in the `ipa-enrollment` SLAPI plugin. A remote authenticated client can exploit a null pointer dereference vulnerability by sending a malformed Lightweight Directory Access Protocol (LDAP) extended operation. By omitting the request value for the `JOIN_OID` in the `ipa-enrollment` extended operation, an attacker can trigger a server crash, potentially causing a denial of service.
