CVE-2026-111163

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.
