UBUNTU-CVE-2024-50003: Medium severity ubuntu/linux-hwe-edge vulnerability

Published Oct 21, 2024
·
Updated

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix system hang while resume with TBT monitor [Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume. The TBT monitor HPD will be triggered during the resume procedure and call the drmclientmodesetprobe() while struct drmconnector connector->dev->master is NULL. It will mess up the pipe topology after resume. [How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default. (cherry picked from commit 453f86a26945207a16b8f66aaed5962dc2b95b85)

Frequently Asked Questions

1

Which systems are realistically exposed to this issue?

Systems using the listed Ubuntu kernel packages are exposed when an AMD display setup has a Thunderbolt monitor connected and the system is suspended and resumed. The reported impact is a system hang during resume.

2

What conditions trigger the hang?

A Thunderbolt monitor HPD event must occur during the resume procedure. In that state, the event can invoke drm_client_modeset_probe() while connector->dev->master is NULL, corrupting pipe topology after resume.

3

Are default resume connector probes relevant to mitigation?

Yes. The fix skips Thunderbolt-monitor HPD handling during resume because connectors are probed after resume by default. If patching cannot be applied immediately, avoiding suspend/resume with a connected Thunderbolt monitor avoids the described trigger.
