More detail: https://alsa.opensrc.org/Alsa-lib\r\n\r\nSecurity Fix(es):\n\nThe Advanced Linux Sound Architecture (ALSA) library before 1.2.16.1 contains a double-free vulnerability in parse_def() in src/conf.c that allows attackers to corrupt memory by supplying maliciously crafted ALSA configuration text. When parsing nested compound or array configuration blocks, parse_def() fails to check return values before continuing, causing snd_config_delete() to be called twice on the same already-freed node, resulting in a NULL-pointer write or invalid memory read.(CVE-2026-56109)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP1","name":"alsa-lib","purl":"pkg:rpm/openEuler/alsa-lib&distro=openEuler-24.03-LTS-SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.10-5.oe2403sp1"}]}],"ecosystem_specific":{"aarch64":["alsa-lib-1.2.10-5.oe2403sp1.aarch64.rpm","alsa-lib-debuginfo-1.2.10-5.oe2403sp1.aarch64.rpm","alsa-lib-debugsource-1.2.10-5.oe2403sp1.aarch64.rpm","alsa-lib-devel-1.2.10-5.oe2403sp1.aarch64.rpm"],"noarch":["alsa-topology-1.2.10-5.oe2403sp1.noarch.rpm","alsa-ucm-1.2.10-5.oe2403sp1.noarch.rpm"],"src":["alsa-lib-1.2.10-5.oe2403sp1.src.rpm"],"x86_64":["alsa-lib-1.2.10-5.oe2403sp1.x86_64.rpm","alsa-lib-debuginfo-1.2.10-5.oe2403sp1.x86_64.rpm","alsa-lib-debugsource-1.2.10-5.oe2403sp1.x86_64.rpm","alsa-lib-devel-1.2.10-5.oe2403sp1.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2850"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56109"}],"database_specific":{"severity":"Medium"}}
