CVE-2024-48426Public exploit

Application crash via invalid mesh postprocessing read

Published Oct 24, 2024 · Updated Oct 29, 2024

Invalid memory access in Assimp 5.4.3 allows local users to crash an importing application via a crafted 3D model file. SortByPTypeProcess::Execute reads an invalid address while sorting meshes by primitive type during postprocessing of malformed scene data. Reachability requires an application to import the supplied model with primitive-type sorting enabled, and the demonstrated consequence is a process crash.
