CVE-2026-52904

CVE-2026-52904 affects the Linux kernel's DRM Nouveau NVKM path. When aperture_remove_conflicting_pci_devices() fails, nvkm_device_pci_new() could leak the device wrapper and pci_enable_device() reference. The fix redirects to the existing fail_nvkm path so nvkm_device_del() runs and balances res...
