CVE-2026-10232Public exploit

Local process memory corruption via malformed ASE tree

Published Jun 1, 2026 · Updated Jun 1, 2026

Use-after-free in Assimp 6.0.0 through 6.0.4 allows local users to crash an importing process with a malformed ASE file. The ASE importer's AddNodes routine shifts mChildren entries forward while inserting a .Target node, overwriting entries and constructing a tree with duplicated or missing child pointers. Recursive aiNode destruction then dereferences an object already freed through that malformed tree; exploitation requires a local process to import the crafted file and is demonstrated to terminate the process.
