{"id":"CVE-2026-46179","summary":"ASoC: SOF: Don't allow pointer operations on unconfigured streams","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: Don't allow pointer operations on unconfigured streams\n\nWhen reporting the pointer for a compressed stream we report the current\nI/O frame position by dividing the position by the number of channels\nmultiplied by the number of container bytes. These values default to 0 and\nare only configured as part of setting the stream parameters so this allows\na divide by zero to be configured. Validate that they are non zero,\nreturning an error if not","modified":"2026-07-15T01:49:17.111174687Z","published":"2026-05-28T09:36:33.062Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46179.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0f0c0c1397a42aacaacae828206ee1b921623952"},{"type":"WEB","url":"https://git.kernel.org/stable/c/327a64241f30c74b6f35537eb9e1fc6c3cbe060b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4f42dd01f5217465f23a763e27b3984e114d0972"},{"type":"WEB","url":"https://git.kernel.org/stable/c/76ff6bfc9a809571793f425ba99f6a759108dcf8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98ed1383f597f8a45b6cb816bb20b96d46eeceda"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c5b6285aae050ff1c3ea824ca3d88ac4be1e69c8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46179.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46179"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"c1a731c71359407eae4fd0a5fd675ef25a582764"},{"fixed":"76ff6bfc9a809571793f425ba99f6a759108dcf8"},{"fixed":"327a64241f30c74b6f35537eb9e1fc6c3cbe060b"},{"fixed":"98ed1383f597f8a45b6cb816bb20b96d46eeceda"},{"fixed":"0f0c0c1397a42aacaacae828206ee1b921623952"},{"fixed":"4f42dd01f5217465f23a763e27b3984e114d0972"},{"fixed":"c5b6285aae050ff1c3ea824ca3d88ac4be1e69c8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46179.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.88"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.30"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46179.json"}}],"schema_version":"1.7.5"}
