UBUNTU-CVE-2025-71141: Medium severity ubuntu/linux-hwe-edge vulnerability

Published Jan 14, 2026
·
Updated

In the Linux kernel, the following vulnerability has been resolved: drm/tilcdc: Fix removal actions in case of failed probe The drmkmshelperpollfini() and drmatomichelpershutdown() helpers should only be called when the device has been successfully registered. Currently, these functions are called unconditionally in tilcdcfini(), which causes warnings during probe deferral scenarios. [ 7.972317] WARNING: CPU: 0 PID: 23 at drivers/gpu/drm/drmatomicstatehelper.c:175 drmatomichelpercrtcduplicatestate+0x60/0x68 ...

Additionally, remove the now-unnecessary isregistered flag.

Frequently Asked Questions

1

What systems are exposed to this issue?

The affected Ubuntu kernel package families listed are linux-riscv, linux-realtime, linux-azure, linux-gcp, linux-azure-fde, linux-hwe-edge, linux-gke, and linux-gkeop. The issue is in the tilcdc DRM driver’s failed-probe cleanup path.

2

What conditions trigger the problem?

The problem occurs when tilcdc device probing fails or is deferred, causing its cleanup routine to call DRM shutdown and polling cleanup helpers before the device has been successfully registered. Exploitation requires local access with low privileges according to the supplied CVSS vector.

3

What is the observed impact?

The reported behavior is kernel warnings and a stack trace during probe-deferral scenarios. The supplied severity vector rates availability impact as high, with no stated confidentiality or integrity impact.

4

What should be done if the issue is observed?

Update the affected Ubuntu kernel package to a version containing the fix. The fix changes failed-probe cleanup so DRM cleanup helpers run only for resources that were successfully initialized and registered.
