Code execution via 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 context-dependent attackers to execute code through a malicious file. Adobe has not disclosed the affected file parser, the unsafe memory operation, or the malformed field that triggers the out-of-bounds write. The victim must open the file, and successful exploitation executes code with the current user's privileges.
