In the Linux kernel, the following vulnerability has been resolved: ALSA:
hda/cs_dsp_ctl: Use private_free for control cleanup Use the control
private_free callback to free the associated data block. This ensures that
the memory won’t leak, whatever way the control gets destroyed. The
original implementation didn’t actually remove the ALSA controls in
hda_cs_dsp_control_remove(). It only freed the internal tracking structure.
This meant it was possible to remove/unload the amp driver while leaving
its ALSA controls still present in the soundcard. Obviously attempting to
access them could cause segfaults or at least dereferencing stale pointers.
