{"id":"AZL-96384","summary":"CVE-2026-74291 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: topology: Check PCM and DAI name strings before use\n\nTopology objects store several PCM and DAI names in fixed-size UAPI\narrays. Other topology parser paths validate these fields with bounded\nstrnlen() checks before using them as C strings, but the PCM and DAI\npaths still pass some fixed-size arrays directly to strlen(),\ndevm_kstrdup(), DAI lookup, and diagnostic prints.\n\nA malformed topology blob with a non-NUL-terminated PCM, DAI, or stream\ncapability name can therefore make the parser read past the end of the\nfixed-size field.\n\nReject unterminated PCM and DAI name fields before consuming them as C\nstrings.","modified":"2026-08-31T05:26:27Z","published":"2026-08-15T06:22:28Z","upstream":["CVE-2026-74291"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74291"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96384.json"}}],"schema_version":"1.9.0"}
