Affected: fluidsynth

FluidSynth is a software synthesizer based on the SoundFont 2 specifications. From 1.1.2 until 2.5.6, the FluidSynth command handler accepts a pitch_bend_range command whose channel argument is not bounds checked before the supplied value is written through the selected synth channel. An out-of-range channel can therefore cause an out-of-bounds heap write, leading to denial of service or possible code execution. The issue is remotely reachable when the TCP server is enabled through new_fluid_server() or fluidsynth -s, and it is locally reachable through malicious commands delivered to the FluidSynth shell on standard input. Applications that do not use the shell, command handler, or TCP server are not affected. This issue is fixed in version 2.5.6.

Affected: Ubuntu:Pro:14.04:LTS: fluidsynth, Ubuntu:Pro:16.04:LTS: fluidsynth, Ubuntu:Pro:18.04:LTS: fluidsynth, Ubuntu:Pro:20.04:LTS: fluidsynth, Ubuntu:Pro:22.04:LTS: fluidsynth, Ubuntu:Pro:24.04:LTS: fluidsynth, Ubuntu:Pro:26.04:LTS: fluidsynth

It was discovered that FluidSynth did not properly validate the channel argument of the pitch_bend_range command. A remote attacker could possibly use this issue to cause FluidSynth to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-58264)

It was discovered that FluidSynth incorrectly handled configurations with more than 16 MIDI channels in its MIDI player, leading to a heap buffer overflow. An attacker could possibly use this issue to cause FluidSynth to crash, resulting in a denial of service, or execute arbitrary code. This issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-61714)
