"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nipvlan: Fix out-of-bound bugs caused by unset skb-\u003emac_header\n\nIf an AF_PACKET socket is used to send packets through ipvlan and the\ndefault xmit function of the AF_PACKET socket is changed from\ndev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option\nname of PACKET_QDISC_BYPASS, the skb-\u003emac_header may not be reset and\nremains as the initial value of 65535, this may trigger slab-out-of-bounds\nbugs as following:\n\n=================================================================\nUG: KASAN: slab-out-of-bounds in ipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan]\nPU: 2 PID: 1768 Comm: raw_send Kdump: loaded Not tainted 6.0.0-rc4+ #6\nardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33\nall Trace:\nprint_address_description.constprop.0+0x1d/0x160\nprint_report.cold+0x4f/0x112\nkasan_report+0xa3/0x130\nipvlan_xmit_mode_l2+0xdb/0x330 [ipvlan]\nipvlan_start_xmit+0x29/0xa0 [ipvlan]\n__dev_direct_xmit+0x2e2/0x380\npacket_direct_xmit+0x22/0x60\npacket_snd+0x7c9/0xc40\nsock_sendmsg+0x9a/0xa0\n__sys_sendto+0x18a/0x230\n__x64_sys_sendto+0x74/0x90\ndo_syscall_64+0x3b/0x90\nentry_SYSCALL_64_after_hwframe+0x63/0xcd\n\nThe root cause is:\n 1. packet_snd() only reset skb-\u003emac_header when sock-\u003etype is SOCK_RAW\n and skb-\u003eprotocol is not specified as in packet_parse_headers()\n\n 2. packet_direct_xmit() doesn\u0027t reset skb-\u003emac_header as dev_queue_xmit()\n\nIn this case, skb-\u003emac_header is 65535 when ipvlan_xmit_mode_l2() is\ncalled. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which\nuse \"skb-\u003ehead + skb-\u003emac_header\", out-of-bound access occurs.\n\nThis patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()\nand reset mac header in multicast to solve this out-of-bound bug.",
