Technical details

The vulnerability is an out-of-bounds read in Adobe Substance 3D Painter's file processing logic. It occurs when the application parses a specially crafted malicious file without proper bounds checking on memory access. The attack requires user interaction (opening a malicious file) but does not require authentication or network access. A successful exploit allows an attacker to read adjacent memory regions, potentially disclosing sensitive information such as encryption keys, design data, or system configuration details. Adobe has released a security advisory (APSB26-129) with patch information.
