CVE-2026-2653Public exploit

Process crash via invalid STL facet count

Published Feb 18, 2026 · Updated Feb 18, 2026

Heap-based buffer overflow in ADMesh 0.98.0 through 0.98.5 allows local users to crash the process via a crafted STL file. An invalid facet count reaches allocation and normal-direction processing without adequate validation, leaving facet storage undersized before stl_calculate_normal reads four bytes outside the heap allocation. Execution requires local access to run ADMesh on the file; the demonstrated consequence is a process abort, while code execution is not established.
