Technical details
The vulnerability is a NULL pointer dereference in Substance 3D Painter versions 11.1.2 and earlier. The flaw occurs when the application processes a malformed or specially crafted file without properly validating pointer references before dereferencing them. Exploitation requires user interaction: a victim must open a malicious file, typically a project or texture asset. A successful exploit results in application crash and denial-of-service, but does not enable code execution or data theft. Adobe has issued security advisory APSB26-25 with patched versions.
