CVE-2023-26349

Sensitive-memory disclosure via stale USDZ object use

Published Mar 28, 2023 · Updated Mar 5, 2025

Use-after-free in Adobe Dimension 3.4.7 and earlier allows remote attackers to disclose sensitive memory through a malicious USDZ file. The USDZ parser fails to verify that an object still exists before operating on it, causing reuse of freed memory during file parsing. Exploitation requires a user to open the crafted file; disclosed memory can expose address data that weakens ASLR, without reported direct integrity or availability impact.
