Vulnerability from github – Published: 2024-07-10 09:30 – Updated: 2025-09-17 18:31

Details

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.

Severity ?

5.5 (Medium)
