CVE-2026-52904

high

Description

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix nvkm_device leak on aperture removal failure When aperture_remove_conflicting_pci_devices() fails during probe, the error path returns directly without unwinding the nvkm_device that was just allocated by nvkm_device_pci_new(). This leaks both the device wrapper and the pci_enable_device() reference taken inside it. Jump to the existing fail_nvkm label so nvkm_device_del() runs and balances both. The leak was introduced when the intermediate nvkm_device_del() between detection and aperture removal was dropped in favor of creating the pci device once.
