CVE-2026-57224

A flaw was found in Suricata. The DHCP and RDP parsers fail to record packet direction for stateless transactions. This allows a network sensor observing only one direction of traffic to accumulate an unbounded list of per-flow transactions. Consequently, this leads to increasing CPU and memory...

DEBIAN-CVE-2026-57224

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the DHCP parser in rust/src/dhcp/dhcp.rs creates stateless transactions without recording their packet direction with AppLayerTxData::fordirection, so a...

CVE-2026-57224

Suricata versions 8.0.0 through 8.0.6 are affected by a denial-of-service vulnerability in the DHCP parser (rust/src/dhcp/dhcp.rs) and RDP parser (rust/src/rdp/rdp.rs). Both parsers create stateless transactions without recording packet direction via AppLayerTxData::for_direction(). When a sensor...
