CVE-2026-61720 FluidSynth: SF2 DMOD Chunk Unsigned Underflow
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-2026-61723 FluidSynth: DLS ptbl Chunk Integer Overflow
FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 2.5.0 until 2.5.6, the native DLS parser validates ptbl chunks with the unsigned expression cues 4 + cbsize without checking whether the multiplication and addition fit in 32 bits. A crafted DLS file can supply a...
CVE-2026-61723
FluidSynth (a software synthesizer based on the SoundFont 2 specifications) versions 2.5.0 through 2.5.6 are affected by an integer overflow in the native DLS parser's ptbl chunk validation. The expression cues * 4 + cbsize uses 32-bit unsigned arithmetic without bounds checking; with cues = 0x40...
