Code execution via uninitialized SBS parser memory
Published Jun 15, 2023 · Updated Mar 5, 2025
Access of uninitialized pointer in Adobe Substance 3D Designer 12.4.1 and earlier allows remote attackers to execute code via an SBS file. The SBS parser accesses memory without properly initializing it, and the resulting invalid pointer state enables code execution. Exploitation requires a victim to open a malicious file or visit a malicious page, and the code runs with the current user's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
