GHSA-7W3C-254R-4WJ3

Vulnerability from github – Published: 2026-08-28 09:31 – Updated: 2026-08-28 09:31

Details

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.

Detection rules are retrieved from Rulezet.

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.
