In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: Fix runtime PM leak in nouveau_connector_detect() If… (CVE-2026-98513)

The Linux kernel's drm/nouveau driver contained a flaw in nouveau_connector_detect() where an early return on failure of nvif_outp_edid_get() did not drop the runtime PM reference taken at the start of the function. This caused a runtime PM leak, keeping the device powered on longer than intended. The fix balances the runtime PM reference on the error path to prevent the leak.

The vulnerability causes a runtime power management reference leak, which results in the device remaining powered on unnecessarily. This can lead to increased power consumption and potentially reduced battery life on affected systems. There is no indication of direct security compromise or exploitation in the wild.

A fix has been applied to the Linux kernel to properly balance the runtime PM reference in nouveau_connector_detect(). Users should update to the fixed kernel version when available. Patch status is not explicitly stated in the provided data; check the vendor or Linux kernel advisories for the exact fixed versions and update accordingly.
