NewCVE-2026-22258 (opens in a new tab)How to fix?
Upgrade suricata to version 7.0.14, 8.0.3 or higher.
Overview
suricata is a network IDS, IPS and NSM engine developed by the OISF and the Suricata community.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via unbounded buffering in the fragment process. An attacker can cause memory exhaustion and termination of the process by sending specially crafted DCERPC traffic. This is only exploitable if the stream.reassembly.depth setting is not configured to limit the amount of buffered data for DCERPC over TCP or SMB.
Workaround
This vulnerability can be mitigated by disabling the DCERPC/UDP parser or by setting a limit on the stream.reassembly.depth parameter for DCERPC over TCP and SMB.
