CVE-2026-52904
drm/nouveau: fix nvkm_device leak on aperture removal failure
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.

Action Type Old Value New Value Added Translation Title: Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: drm/nouveau: corregir fuga de nvkm_device al fallar la eliminación de la apertura Cuando aperture_remove_conflicting_pci_devices() falla durante la sonda, la ruta de error regresa directamente sin desenrollar el nvkm_device que acababa de ser asignado por nvkm_device_pci_new(). Esto fuga tanto el envoltorio del dispositivo como la referencia de pci_enable_device() tomada dentro de él. Saltar a la etiqueta fail_nvkm existente para que nvkm_device_del() se ejecute y equilibre ambos. La fuga fue introducida cuando el nvkm_device_del() intermedio entre la detección y la eliminación de la apertura fue eliminado en favor de crear el dispositivo pci una sola vez. -
