Name of the Vulnerable Software and Affected Versions:

Linux kernel (affected versions not specified)

Description:

A flaw exists in the Linux kernel related to the ALSA subsystem and the tas2781 driver. A wrong reference to `tasdevice priv` was set to `h->hda priv` instead of `h->priv` during calibration data management unification. This resulted in memory corruption and potential system crashes. The issue stems from the use of a void pointer, which prevented the compiler from detecting the error.

Recommendations:

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
