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-terminat…
