CVE-2026-111161
libADLMIDI 1.6.2 through 1.6.2.1 contains an off-by-one stack out-of-bounds write vulnerability in BW_MidiSequencer that allows attackers to corrupt stack memory via crafted MIDI files.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
Description
libADLMIDI 1.6.2 through 1.6.2.1 contains an off-by-one stack out-of-bounds write vulnerability in BW_MidiSequencer that allows attackers to corrupt stack memory via crafted MIDI files. Attackers can supply a MIDI file with a note-on using status 0x9F and note 0x7F through adl_openFile() or adl_openData() to crash the hosting media player or game engine.
