CVE-2026-45752

Suricata detect/transform: use-after-free in decompress transforms PUBLISHED

Description (CNA)

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, when certain detection transforms are chained, the decompress transform pipeline could read from an inspection buffer after it had been reallocated and freed. The issue is reached during network traffic processing, but requires a malicious rule as Suricata will crash whatever the traffic. Version 8.0.5 contains a fix. As a workaround, avoid rules that chain `gunzip` or `zlib_deflate` with `max-size` bigger than 4096 after another transform.
