Title
ASoC: wm_adsp: Fix NULL dereference when removing firmware controls
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: wm_adsp: Fix NULL dereference when removing firmware controls
In wm_adsp_control_remove() check that the priv pointer is not NULL
before attempting to cleanup what it points to.
When cs_dsp creates a control it calls wm_adsp_control_add_cb() so that
wm_adsp can create its own private control data. There are two cases
where private data is not created:
1. The control is a SYSTEM control, so an ALSA control is not created.
2. The codec driver has registered a control_add() callback that
hides the control, so wm_adsp_control_add() is not called.
When cs_dsp_remove destroys its control list it calls
wm_adsp_control_remove() for each control. But wm_adsp_control_remove()
was attempting to cleanup the private data pointed to by cs_ctl->priv
without checking the pointer for NULL.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
