AI-suggested

A fix is available in the Linux kernel commits identified by the fixedVersions hashes. Users should update their Linux kernel to a version that includes these fixes to mitigate the vulnerability.

Description

A vulnerability in the Linux kernel's ASoC topology parser allowed reading beyond fixed-size arrays due to missing checks for NUL termination in PCM and DAI name strings. This flaw was fixed by rejecting unterminated PCM and DAI name fields before use.
