Si el controlador hv_netvsc se descarga y se vuelve a cargar, el controlador NET_DEVICE_REGISTER no puede realizar el registro VF exitosamente ya que la llamada de registro se recibe antes de que finalice netvsc_probe. Esto se debe a que registramos Register_netdevice_notifier() muy temprano (incluso antes de vmbus_driver_register()). Para solucionar este problema, intentamos registrar cada VF coincidente (si es visible como un dispositivo de red) al final de netvsc_probe."}], "id": "CVE-2024-26820", "lastModified": "2024-11-21T09:03:08.843", "metrics": {}, "published": "2024-04-17T10:15:08.867", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/309ef7de5d840e17607e7d65cbf297c0564433ef"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/4d29a58d96a78728cb01ee29ed70dc4bd642f135"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/5b10a88f64c0315cfdef45de0aaaa4eef57de0b7"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/9cae43da9867412f8bd09aee5c8a8dc5e8dc3dc2"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/a71302c8638939c45e4ba5a99ea438185fd3f418"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/b6d46f306b3964d05055ddaa96b58cd8bd3a472c"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/bcb7164258d0a9a8aa2e73ddccc2d78f67d2519d"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/c7441c77c91e47f653104be8353b44a3366a5366"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/309ef7de5d840e17607e7d65cbf297c0564433ef"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/4d29a58d96a78728cb01ee29ed70dc4bd642f135"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/5b10a88f64c0315cfdef45de0aaaa4eef57de0b7"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/9cae43da9867412f8bd09aee5c8a8dc5e8dc3dc2"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/a71302c8638939c45e4ba5a99ea438185fd3f418"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/b6d46f306b3964d05055ddaa96b58cd8bd3a472c"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/bcb7164258d0a9a8aa2e73ddccc2d78f67d2519d"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://git.kernel.org/stable/c/c7441c77c91e47f653104be8353b44a3366a5366"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Awaiting Analysis"}
