CVE-2026-98513

A flaw was found in the Linux kernel's Nouveau graphics driver. When the driver fails to retrieve display information during connector detection, it returns without releasing an acquired runtime Power Management (PM) reference. A local user can trigger this issue to cause a resource leak, preventing the graphics device from entering low-power suspend states and causing increased power consumption.

This vulnerability is classified as Low severity because it requires local access and only impacts power management states, preventing supported hardware from entering deep sleep modes without affecting system confidentiality, integrity, or general availability. The flaw specifically targets environments running the Nouveau open-source graphics driver with physical NVIDIA hardware attached. Under typical enterprise deployments, headless servers and virtualization hosts do not load this driver, significantly restricting potential exposure.
