{"id":"UBUNTU-CVE-2026-90781","details":"alsa-lib through 1.2.16.1 contains a stack buffer overflow in the __snd_ctl_ascii_elem_id_parse() function that writes one byte past a 64-byte buffer when parsing a name= field with 64 or more characters. Attackers can supply a long control-element identifier string through saved state files or command-line arguments to overwrite adjacent stack memory and crash the calling process.","modified":"2026-09-16T14:03:31.095170596Z","published":"2026-09-13T13:16:00Z","upstream":["CVE-2026-90781"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-90781"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-90781"},{"type":"REPORT","url":"https://lore.kernel.org/alsa-devel/CACBQ=P2FhO3M6dkv3cWuKb6Qhs92ouV+FJ3SJZ_PVBSSdJWRAQ@mail.gmail.com/"}],"affected":[{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.27.2-1ubuntu6","1.0.27.2-1ubuntu7","1.0.27.2-3ubuntu1","1.0.27.2-3ubuntu2","1.0.27.2-3ubuntu5","1.0.27.2-3ubuntu6","1.0.27.2-3ubuntu7"],"ecosystem_specific":{"binaries":[{"binary_name":"libasound2","binary_version":"1.0.27.2-3ubuntu7"},{"binary_version":"1.0.27.2-3ubuntu7","binary_name":"libasound2-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.0.29-0ubuntu1","1.1.0-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.0-0ubuntu1","binary_name":"libasound2"},{"binary_version":"1.1.0-0ubuntu1","binary_name":"libasound2-data"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.3-5","1.1.3-5ubuntu0.1","1.1.3-5ubuntu0.2","1.1.3-5ubuntu0.4","1.1.3-5ubuntu0.5","1.1.3-5ubuntu0.6"],"ecosystem_specific":{"binaries":[{"binary_version":"1.1.3-5ubuntu0.6","binary_name":"libasound2"},{"binary_name":"libasound2-data","binary_version":"1.1.3-5ubuntu0.6"},{"binary_name":"libasound2-plugin-smixer","binary_version":"1.1.3-5ubuntu0.6"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=esm-infra%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.9-0ubuntu1","1.2.1.2-2ubuntu2","1.2.2-2ubuntu1","1.2.2-2.1","1.2.2-2.1ubuntu1","1.2.2-2.1ubuntu2","1.2.2-2.1ubuntu2.1","1.2.2-2.1ubuntu2.2","1.2.2-2.1ubuntu2.3","1.2.2-2.1ubuntu2.4","1.2.2-2.1ubuntu2.5","1.2.2-2.1ubuntu2.5+esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.2-2.1ubuntu2.5+esm1","binary_name":"libasound2"},{"binary_name":"libasound2-data","binary_version":"1.2.2-2.1ubuntu2.5+esm1"},{"binary_name":"libasound2-plugin-smixer","binary_version":"1.2.2-2.1ubuntu2.5+esm1"},{"binary_name":"libatopology2","binary_version":"1.2.2-2.1ubuntu2.5+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.4-1.1ubuntu3","1.2.4-1.1ubuntu4","1.2.5.1-1ubuntu1","1.2.6.1-1ubuntu1","1.2.6.1-1ubuntu1.1","1.2.6.1-1ubuntu1.2"],"ecosystem_specific":{"binaries":[{"binary_name":"libasound2","binary_version":"1.2.6.1-1ubuntu1.2"},{"binary_name":"libasound2-data","binary_version":"1.2.6.1-1ubuntu1.2"},{"binary_version":"1.2.6.1-1ubuntu1.2","binary_name":"libasound2-plugin-smixer"},{"binary_version":"1.2.6.1-1ubuntu1.2","binary_name":"libatopology2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.9-2","1.2.10-1","1.2.10-2","1.2.10-3","1.2.10-3build1","1.2.11-1build1","1.2.11-1build2","1.2.11-1ubuntu0.1","1.2.11-1ubuntu0.2","1.2.11-1ubuntu0.3"],"ecosystem_specific":{"binaries":[{"binary_name":"libasound2-data","binary_version":"1.2.11-1ubuntu0.3"},{"binary_name":"libasound2-plugin-smixer","binary_version":"1.2.11-1ubuntu0.3"},{"binary_name":"libasound2t64","binary_version":"1.2.11-1ubuntu0.3"},{"binary_name":"libatopology2t64","binary_version":"1.2.11-1ubuntu0.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-90781.json"}},{"package":{"name":"alsa-lib","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/alsa-lib?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions"
