The index is the smpno field of a parsed MIDI event, which is initialised to zero and only later overwritten from a program-change parameter, so an event reaching the note test before an instrument is assigned carries zero. A 32-byte MIDI file supplied to the library&apos;s public ModPlug_Load entry point drives the path through CSoundFile::Create, CSoundFile::ReadMID, and MID_ReadPatterns to the read. The byte read out of bounds determines whether a note event is treated as looping, so adjacent static storage influences playback state.(CVE-2026-75904)","affected":[{"package":{"ecosystem":"openEuler:20.03-LTS-SP4","name":"libmodplug","purl":"pkg:rpm/openEuler/libmodplug&distro=openEuler-20.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.9.0-11.oe2003sp4"}]}],"ecosystem_specific":{"aarch64":["libmodplug-0.8.9.0-11.oe2003sp4.aarch64.rpm","libmodplug-debuginfo-0.8.9.0-11.oe2003sp4.aarch64.rpm","libmodplug-debugsource-0.8.9.0-11.oe2003sp4.aarch64.rpm","libmodplug-devel-0.8.9.0-11.oe2003sp4.aarch64.rpm"],"src":["libmodplug-0.8.9.0-11.oe2003sp4.src.rpm"],"x86_64":["libmodplug-0.8.9.0-11.oe2003sp4.x86_64.rpm","libmodplug-debuginfo-0.8.9.0-11.oe2003sp4.x86_64.rpm","libmodplug-debugsource-0.8.9.0-11.oe2003sp4.x86_64.rpm","libmodplug-devel-0.8.9.0-11.oe2003sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3603"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75904"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}],"database_specific":{"severity":"Low"}}
