Description OSIDB Bzimport 2025-09-05 18:04:07 UTC
In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda: tas2781: Fix wrong reference of tasdevice_priv

During the conversion to unify the calibration data management, the
reference to tasdevice_priv was wrongly set to h->hda_priv instead of
h->priv.  This resulted in memory corruption and crashes eventually.
Unfortunately it's a void pointer, hence the compiler couldn't know
that it's wrong.
