CVE-2025-14958Public exploit

Application crash via negative vertex-buffer index

Published Dec 19, 2025 · Updated Dec 19, 2025

Heap-based buffer overflow in sokol_gfx.h allows local users to crash applications that embed affected floooh sokol code. _sg_pipeline_common_init checks buffer_index only against the upper limit, so a negative index reaches vertex_buffer_layout_active and writes before the allocated array. Reachability requires an embedding application to pass a negative vertex-buffer index through sg_make_pipeline; the demonstrated consequence is an AddressSanitizer-detected process abort.
