CVE-2025-3160Public exploit

Crash via unchecked null scene-node dereference

Published Apr 3, 2025 · Updated Apr 3, 2025

Out-of-bounds read in Assimp 5.4.3 allows context-dependent attackers to crash an importing process using a malformed 3D model. The AddNodeHashes routine recursively receives a null aiNode and reads node->mName.length without first validating the pointer. Exploitation requires a crafted file to be imported; the published proof of concept crashes under AddressSanitizer and does not achieve standalone code execution.
