CVE-2026-61722 FluidSynth: DLS Articulation 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 articulation chunks using the unsigned expression cbsize + connblocks 12 without first ensuring that the multiplication and addition fit in 32 bits. A crafted DLS...
