CVE-2026-80658

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove()

Attempting to access driver data in the platform driver ->remove()

callback may lead to a null pointer dereference since there is no

guaranty that the component ->bind() callback invoking

platform_set_drvdata() was executed.

A common scenario is when Rockchip DRM driver didn't manage to run

component_bind_all() because of an (unrelated) error causing early

return from rockchip_drm_bind().

Drop the unnecessary call to platform_get_drvdata() and, instead,

reference the target device structure via platform_device.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
