CVE-2026-15184Public exploit

Local process crash via unchecked entity reference

Published Jul 9, 2026 · Updated Jul 9, 2026

Null pointer dereference in GNU LibreDWG 0.13.0 through 0.13.4 allows local users to crash dwggrep with a malformed DWG file. In src/dwg.c, dwg_next_entity dereferences next_obj after dwg_ref_object_silent returns NULL for an invalid absolute entity reference. The user must invoke DWG processing on attacker-controlled input; the demonstrated consequence is termination of that process, not code execution or system-wide shutdown.
