In the Linux kernel, the following vulnerability has been resolved:

ASoC: topology: Check PCM and DAI name strings before use

Topology objects store several PCM and DAI names in fixed-size UAPI arrays. Other topology parser paths validate these fields with bounded strnlen() checks before using them as C strings, but the PCM and DAI paths still pass some fixed-size arrays directly to strlen(), devm_kstrdup(), DAI lookup, and diagnostic prints.

A malformed topology blob with a non-NUL-terminated PCM, DAI, or stream capability name can therefore make the parser read past the end of the fixed-size field.

Reject unterminated PCM and DAI name fields before consuming them as C strings.
