Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The Linux kernel contains a flaw within the ASoC (Audio System on Chip) Intel bytcr rt5640 driver. Passing an invalid value through a quirk option currently results in an error message but does not correct the input. This can potentially lead to out-of-bounds (OOB) access. A patch has been implemented to correct the input mapping to a default value when an invalid value is provided.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
