Description OSIDB Bzimport 2026-04-02 15:01:05 UTC 
Suricata is a network IDS, IPS and NSM engine. Prior to versions 7.0.15 and 8.0.4, flooding of craft HTTP2 continuation frames can lead to memory exhaustion, usually resulting in the Suricata process being shut down by the operating system. This issue has been patched in versions 7.0.15 and 8.0.4.
