CyberRota Analysis
AI-GeneratedSuricata versions prior to 8.0.7 are vulnerable to a type confusion issue in the DoH2 implementation, leading to potential memory corruption due to improper cleanup of HTTP2 state when handling requests that upgrade from HTTP1 to HTTP2. This vulnerability can result in an invalid free, posing a critical risk of exploitation. Organizations utilizing Suricata with the app-layer.protocols.doh2 feature enabled should prioritize patching to mitigate this severe threat.

Original NVD Description
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.
