    CVE-2025-54065 (GCVE-0-2025-54065)

    Vulnerability from nvd – Published: 2025-12-03 17:02 – Updated: 2025-12-03 21:39

    Title
    GZDoom engine allows arbitrary code execution via ZScript actor states
    Summary
    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.
