CVE-2026-98513: drm/nouveau: Fix runtime PM leak in nouveau_connector_detect()

Published Oct 18, 2026

Updated

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

drm/nouveau: Fix runtime PM leak in nouveauconnectordetect()

If nvifoutpedidget() fails, nouveauconnectordetect() returns early without dropping the runtime PM reference taken at the start of the function, keeping the device powered on until the next successful detect.

Balance the reference on the error path like the other exit paths do.

Frequently Asked Questions

1

What is the practical impact if this issue is triggered?

A failed EDID retrieval during connector detection can leave an extra runtime power-management reference held. The affected device may remain powered on until a later connector detection succeeds, causing unnecessary power use.

2

What condition triggers the leaked runtime PM reference?

The leak occurs when nvif_outp_edid_get() fails during nouveau_connector_detect(). The function then takes an early error return without releasing the runtime PM reference acquired at its start.

3

Can the device recover without a reboot?

Yes. The description states that the device remains powered on until the next successful connector detect, which can balance the condition.
