CVE-2023-26414

Code execution via use-after-free in USD parser

Published Apr 13, 2023 · Updated Mar 5, 2025

Use-after-free in Adobe Substance 3D Designer 12.4.0 and earlier allows remote attackers to execute code through a malicious USD file. During USD parsing, crafted file data causes the application to access an object after its memory has been freed. A victim must open the file, after which attacker-controlled code runs with the current user's privileges.
