CVE-2026-111162 Details
Description
WildMIDI through 0.5.0 contains a heap out-of-bounds read vulnerability in the HMP parser _WM_ParseNewHmp() that allows attackers to read beyond buffers via underflowed chunk lengths. Attackers can supply a crafted .hmp file with a chunk length of 0-12 that wraps to roughly 4 GB, crashing applications or exposing heap bytes through WildMidi_GetInfo().
A heap out-of-bounds read vulnerability has been identified in WildMIDI versions through 0.5.0, specifically within the HMP parser function '_WM_ParseNewHmp()'. This vulnerability allows attackers to read beyond allocated buffers by exploiting underflowed chunk lengths. By supplying a crafted .hmp file that manipulates the chunk length to a value between 0 and 12, attackers can cause the length to wrap around to approximately 4 GB. This exploitation can lead to application crashes or the exposure of heap memory contents through the WildMidi_GetInfo() function.
Users can update to WildMIDI version 0.5.1 or later, where this vulnerability has been fixed.
