Application crash via unchecked null root node
Published Oct 24, 2024 · Updated Oct 28, 2024
Null-pointer dereference in Open Asset Import Library Assimp 5.4.3 and earlier allows local users to crash applications via malformed 3D models. SplitLargeMeshesProcess_Triangle::UpdateNode reads through the scene root-node pointer without first rejecting a null root during mesh post-processing. A consuming application must process attacker-controlled model data with large-mesh splitting enabled; the demonstrated consequence is process termination, with no reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
