Vulnerability from github – Published: 2024-03-26 18:32 – Updated: 2025-03-17 15:31

Details

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

drm/amd/display: Wake DMCUB before executing GPINT commands

[Why] DMCUB can be in idle when we attempt to interface with the HW through the GPINT mailbox resulting in a system hang.

[How] Add dc_wake_and_execute_gpint() to wrap the wake, execute, sleep sequence.

If the GPINT executes successfully then DMCUB will be put back into sleep after the optional response is returned.

It functions similar to the inbox command interface.

Severity

7.8 (High)

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.
