CVE-2026-111155
libTiMidity through 0.2.8 contains a heap out-of-bounds read vulnerability in the SoundFont loader in src/sndfont.c that uses unvalidated sampleId and instrument generator values as table indices.
Does this matter?
Lower severity and a low EPSS score (0.13%). Track it; it rarely justifies an emergency change on its own.
Description
libTiMidity through 0.2.8 contains a heap out-of-bounds read vulnerability in the SoundFont loader in src/sndfont.c that uses unvalidated sampleId and instrument generator values as table indices. Attackers can supply a crafted .sf2 file loaded through mid_set_soundfont() to read heap memory out of bounds and crash the application.
