CVE-2026-94083 (opens in a new tab)How to fix?
Upgrade Debian:unstable suricata to version 1:8.0.7-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream suricata package and not the suricata package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
