      "summary": "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.",
