  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxen/netfront: drop RX packets with a short Ethernet header\n\nhandle_incoming_queue() pulls pull_to bytes into the head before\ncalling eth_type_trans().  pull_to is the length of the first RX slot,\ncapped at RX_COPY_THRESHOLD, and that length comes from the backend.\nNothing checks it against ETH_HLEN.\n\nIf the first slot is shorter than ETH_HLEN and more slots follow, the\nhead ends up shorter than an Ethernet header while skb-\u003elen is longer,\nand eth_type_trans() BUG()s in __skb_pull().  If the whole packet is\nshorter than ETH_HLEN, eth_type_trans() reads the header past the end\nof the data instead.\n\nPull at least ETH_HLEN, and drop the packet if that fails, which also\ndrops packets too short to hold an Ethernet header.  This also checks\nthe return value of the pull, which was ignored.",
