CVE-2025-44906Public exploit

Crash via stale JPEG section pointer write

Published May 30, 2025 · Updated May 30, 2025

Heap use-after-free in jhead 3.08 allows attackers to crash the application when a local user processes a crafted JPEG file. ProcessFile retains a JPEG section pointer after CheckSectionsAllocated reallocates the section storage, then memcpy writes 19 bytes through the stale pointer. Exploitation requires local processing of the crafted file; an application abort is demonstrated, while code execution is reported but not demonstrated.
