"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mediatek: Fix potential NULL pointer dereference in dummy net_device handling\n\nMove the freeing of the dummy net_device from mtk_free_dev() to\nmtk_remove().\n\nPreviously, if alloc_netdev_dummy() failed in mtk_probe(),\neth->dummy_dev would be NULL. The error path would then call\nmtk_free_dev(), which in turn called free_netdev() assuming dummy_dev\nwas allocated (but it was not), potentially causing a NULL pointer\ndereference.\n\nBy moving free_netdev() to mtk_remove(), we ensure it's only called when\nmtk_probe() has succeeded and dummy_dev is fully allocated. This\naddresses a potential NULL pointer dereference detected by Smatch[1]."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: mediatek: corrige la posible desreferencia del puntero NULL en el manejo del net_device ficticio. Mueva la liberaci\u00f3n del net_device ficticio de mtk_free_dev() a mtk_remove(). Anteriormente, si alloc_netdev_dummy() fallaba en mtk_probe(), eth->dummy_dev ser\u00eda NULL. La ruta de error luego llamar\u00eda a mtk_free_dev(), que a su vez llamar\u00eda a free_netdev() suponiendo que dummy_dev estuviera asignado (pero no lo estaba), causando potencialmente una desreferencia del puntero NULL. Al mover free_netdev() a mtk_remove(), nos aseguramos de que solo se llame cuando mtk_probe() haya tenido \u00e9xito y dummy_dev est\u00e9 completamente asignado. Esto soluciona una posible desreferencia de puntero NULL detectada por Smatch[1]."
