CVE-2026-48425

User-assisted code execution via heap buffer overflow

Published Aug 25, 2026 · Updated Aug 27, 2026

Heap-based buffer overflow in Adobe Substance 3D Sampler 6.0.1 and earlier allows attackers to execute code via a malicious file. Adobe identifies the weakness class but has not disclosed the affected parser, file format, or heap operation that mishandles the file. Execution requires a user to open the file and runs in that user's context, with no reported network-only path.
