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