Code execution via malicious file out-of-bounds write
Published Jun 9, 2026 · Updated Jun 9, 2026
Out-of-bounds write in Adobe Substance 3D Sampler 6.0.0 and earlier allows attackers to execute code through a malicious file. Adobe has not published the affected parser, file format, or the operation that writes beyond the destination buffer. Exploitation requires a user to open the file, and resulting code runs only in the context of that user.
