CVE-2026-111156

libTiMidity through 0.2.8 contains an out-of-bounds access vulnerability in init_soundfont() in src/sndfont.c that allows attackers to corrupt memory by supplying unvalidated SF2 preset header bank and preset values. Attackers can craft a .sf2 file whose bank or preset indexes past the 128-entry tonebank or drumset arrays, causing heap memory reads, writes, and application crashes.
