Recommendation: Monitor — no exploitation signal at the moment.

In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: bytcr_rt5651: Fix invalid quirk input mapping When an invalid value is passed via quirk option, currently bytcr_rt5640 driver just ignores and leaves as is, which may lead to unepxected results like OOB access. This patch adds the sanity check and corrects the input mapping to the certain default value if an invalid value is passed.
