CVE-2026-111163 Details
Description
WildMIDI through 0.5.0 contains a heap out-of-bounds read vulnerability in _WM_ParseNewHmi() in src/f_hmi.c that reads past buffers when handling 0xfe sub-events. Attackers can supply a crafted HMI file placing a 0xfe 0x10 sub-event near the buffer end to read up to four bytes past the allocation, crashing the decoding application.
A heap out-of-bounds read vulnerability has been identified in WildMIDI versions through 0.5.0. The issue resides in the HMI parser function '_WM_ParseNewHmi' within 'src/f_hmi.c'. This vulnerability allows attackers to craft HMI files that, when processed, read past the allocated buffer by up to four bytes. The exploitation occurs by placing a specific sub-event near the buffer's end, leading to a crash of the application decoding the HMI file.
Users can upgrade to WildMIDI version 0.5.1 or later, where this vulnerability has been fixed.
