CVE-2025-11275Public exploit

Process crash via out-of-bounds separator scan

Published Oct 5, 2025 · Updated Feb 24, 2026

Heap-based buffer overflow in Assimp 6.0.2 allows local users to crash a consuming process with a crafted OpenDDL file. A caller advances the input pointer past the buffer end, after which getNextSeparator tests only for inequality and dereferences the out-of-bounds pointer; the demonstrated consequence is a process crash.
