CVE-2026-18663 389-ds-base: 389-ds-base: pre-authentication double-free in get_ldapmessage_controls_ext() via critical Session Tracking control [fedora-all]

CVE-2026-18663 [MEDIUM] CVE-2026-18663 389-ds-base: 389-ds-base: pre-authentication double-free in get_ldapmessage_controls_ext() via critical Session Tracking control [fedora-all]
CVE-2026-18663 389-ds-base: 389-ds-base: pre-authentication double-free in get_ldapmessage_controls_ext() via critical Session Tracking control [fedora-all]
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.
A flaw was found in 389-ds-base. When parsing LDAP request controls, the get_ldapmessage_controls_ext() function publishes the decoded controls array into the operation's pblock (SLAPI_REQCONTROLS) and then, if a Session Tracking control (OID 1.3.6.1.4.1.21008.108.63.1) is present and marked critical, rejects the request through an error path that frees the controls array via ldap_controls_free() without clearing

Operation teardown in operation_done() subsequently frees the same pointer again through o_params.request_controls, producing a double-free.
Since controls are parsed before authentication (a BIND request suffices) and t
