CVE-2026-61720

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the SF2 parser computes the DMOD modulator count as chunk.size / SFMODSIZE - 1 without rejecting chunks smaller than one record. A crafted SF2 file containing a zero-sized DMOD chunk makes the...

CVE-2026-61720

FluidSynth, a software synthesizer based on the SoundFont 2 specification, is affected by an unsigned integer underflow in its SF2 parser's DMOD chunk handler. When a crafted SF2 file contains a zero-sized DMOD chunk, the expression chunk.size / SF_MOD_SIZE - 1 causes the unsigned subtraction to ...

CVE-2026-61720 FluidSynth: SF2 DMOD Chunk Unsigned Underflow
