CVE-2026-53350
5.5 · MEDIUMOverview
CVE-2026-53350 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 1, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
