CVE-2024-39491
Linux ALSA: HDA cs35l56 DSP Instance Uninitialized Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: cs35l56: Fix lifetime of cs_dsp instance The cs_dsp instance is initialized in the driver probe() so it should be freed in the driver remove(). Also fix a missing call to cs_dsp_remove() in the error path of cs35l56_hda_common_probe(). The call to cs_dsp_remove() was being done in the component unbind callback cs35l56_hda_unbind(). This meant that if the driver was unbound and then re-bound it would be using an uninitialized cs_dsp instance. It is best to initialize the cs_dsp instance in probe() so that it can return an error if it fails. The component binding API doesn't have any error handling so there's no way to handle a failure if cs_dsp was initialized in the bind.
