Detailsinfo

A vulnerability was found in GZDoom up to 4.14.2. It has been classified as problematic. Affected is an unknown function of the component ZScript Actor State Handler. The manipulation with an unknown input leads to a dynamically-managed code resources vulnerability. CWE is classifying the issue as CWE-913. The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

GZDoom is a feature centric port for all Doom engine games. GZDoom is an open source Doom engine. In versions 4.14.2 and earlier, ZScript actor state handling allows scripts to read arbitrary addresses, write constants into the JIT-compiled code section, and redirect control flow through crafted FState and VMFunction structures. A script can copy FState structures into a writable buffer, modify function pointers and state transitions, and cause execution of attacker-controlled bytecode, leading to arbitrary code execution.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-54065 since 07/16/2025. The exploitability is told to be easy. Local access is required to approach this attack. The technical details are unknown and an exploit is not available.
