{"id":"UBUNTU-CVE-2026-16473","details":"A flaw was found in the sbc library (BlueZ SBC codec). An off-by-one error in the SBC frame decoder allows a crafted audio payload to trigger a one-byte heap out-of-bounds read. This could allow an adjacent attacker streaming Bluetooth audio to read a single byte of adjacent heap memory.","modified":"2026-07-29T10:18:11.457267055Z","published":"2026-07-22T11:16:00Z","upstream":["CVE-2026-16473"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-16473"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-16473"}],"affected":[{"package":{"name":"sbc","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.3-1","binary_name":"libsbc1"},{"binary_version":"1.3-1","binary_name":"sbc-tools"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}},{"package":{"name":"sbc","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libsbc1","binary_version":"1.3-2"},{"binary_name":"sbc-tools","binary_version":"1.3-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}},{"package":{"name":"sbc","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.4-1","binary_name":"libsbc1"},{"binary_name":"sbc-tools","binary_version":"1.4-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}},{"package":{"name":"sbc","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5-3build1","1.5-3build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libsbc1","binary_version":"1.5-3build2"},{"binary_name":"sbc-tools","binary_version":"1.5-3build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}},{"package":{"name":"sbc","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0-1","2.0-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsbc1","binary_version":"2.0-1build1"},{"binary_name":"sbc-tools","binary_version":"2.0-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}},{"package":{"name":"sbc","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/sbc?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1-1","2.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsbc1","binary_version":"2.1-1build1"},{"binary_name":"sbc-tools","binary_version":"2.1-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-16473.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
