CVE-2022-38427

Code execution via uninitialized U3D parser pointer

Published Sep 16, 2022 · Updated Apr 23, 2025

Access of an uninitialized pointer in Adobe Photoshop 22.5.8 and earlier and 23.4.2 and earlier allows remote attackers to execute code. The U3D file parser accesses memory through a pointer before initializing it, allowing crafted file content to redirect execution within the Photoshop process. A victim must open a malicious U3D file or visit a page that causes Photoshop to process one; resulting code runs with the current user's privileges.
