Description SMASH SMASH 2026-07-09 14:23:30 UTC 
A vulnerability was found in GNU LibreDWG up to 0.13.4. The impacted element is the function dwg_next_entity of the file src/dwg.c of the component DWG File Handler. Performing a manipulation of the argument next_obj results in null pointer dereference. The attack must be initiated from a local position. The exploit has been made public and could be used. Upgrading to version 0.14 is sufficient to resolve this issue. The patch is named dde45dac3c4d902e4d8fed150a8017b9732019c9. Upgrading the affected component is recommended. Different than CVE-2026-9503.
