Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup<br /> <br /> Use the control private_free callback to free the associated data<br /> block. This ensures that the memory won&amp;#39;t leak, whatever way the<br /> control gets destroyed.<br /> <br /> The original implementation didn&amp;#39;t actually remove the ALSA<br /> controls in hda_cs_dsp_control_remove(). It only freed the internal<br /> tracking structure. This meant it was possible to remove/unload the<br /> amp driver while leaving its ALSA controls still present in the<br /> soundcard. Obviously attempting to access them could cause segfaults<br /> or at least dereferencing stale pointers.
