Actualmente, asignamos un b\u00fafer del kernel de tama\u00f1o nbytes y copiamos nbytes del espacio de usuario a ese b\u00fafer. M\u00e1s adelante, usamos sscanf en este b\u00fafer pero no nos aseguramos de que la cadena termine dentro del b\u00fafer, esto puede provocar una lectura OOB cuando usamos sscanf. Solucione este problema utilizando memdup_user_nul en lugar de memdup_user.\"}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/06cb37e2ba6441888f24566a997481d4197b4e32\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/0f560240b4cc25d3de527deb257cdf072c0102a9\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/1518b2b498a0109eb6b15755169d3b6607356b35\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/6f0f19b79c085cc891c418b768f26f7004bd51a4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/80578ec10335bc15ac35fd1703c22aab34e39fdd\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/8c34096c7fdf272fd4c0c37fe411cd2e3ed0ee9f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/bd502ba81cd1d515deddad7dbc6b812b14b97147\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/e19478763154674c084defc62ae0d64d79657f91\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://lists.debian.org/debian-lts-announce/2024/06/msg00019.html\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}"
