Description OSIDB Bzimport 2025-11-12 11:03:23 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

When an invalid value is passed via quirk option, currently
bytcr_rt5640 driver only shows an error message but leaves as is.
This may lead to unepxected results like OOB access.

This patch corrects the input mapping to the certain default value if
an invalid value is passed.
