CVE-2026-94083 is fixed in suricata on 1 platform by DEBIAN-CVE-2026-94083 (version 1:8.0.7-1), released September 20, 2026. It is not reported as exploited. Patch Radar priority: Urgent.
Suricata before 8.0.7 has a DoH2 type confusion that can cause an invalid free, because cleanup code for the HTTP2 state is executed even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is the default in 8.x versions.
