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.
