"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngeneve: fix header validation in geneve[6]_xmit_skb\n\nsyzbot is able to trigger an uninit-value in geneve_xmit() [1]\n\nProblem : While most ip tunnel helpers (like ip_tunnel_get_dsfield())\nuses skb_protocol(skb, true), pskb_inet_may_pull() is only using\nskb->protocol.\n\nIf anything else than ETH_P_IPV6 or ETH_P_IP is found in skb->protocol,\npskb_inet_may_pull() does nothing at all.\n\nIf a vlan tag was provided by the caller (af_packet in the syzbot case),\nthe network header might not point to the correct location, and skb\nlinear part could be smaller than expected.\n\nAdd skb_vlan_inet_prepare() to perform a complete mac validation.\n\nUse this in geneve for the moment, I suspect we need to adopt this\nmore broadly.\n\nv4 - Jakub reported v3 broke l2_tos_ttl_inherit.sh selftest\n - Only call __vlan_get_protocol() for vlan types.\n\nv2,v3 - Addressed Sabrina comments on v1 and v2\n\n[1]\n\nBUG: KMSAN: uninit-value in geneve_xmit_skb drivers/net/geneve.c:910 [inline]\n BUG: KMSAN: uninit-value in geneve_xmit+0x302d/0x5420 drivers/net/geneve.c:1030\n geneve_xmit_skb drivers/net/geneve.c:910 [inline]\n geneve_xmit+0x302d/0x5420 drivers/net/geneve.c:1030\n __netdev_start_xmit include/linux/netdevice.h:4903 [inline]\n netdev_start_xmit include/linux/netdevice.h:4917 [inline]\n xmit_one net/core/dev.c:3531 [inline]\n dev_hard_start_xmit+0x247/0xa20 net/core/dev.c:3547\n __dev_queue_xmit+0x348d/0x52c0 net/core/dev.c:4335\n dev_queue_xmit include/linux/netdevice.h:3091 [inline]\n packet_xmit+0x9c/0x6c0 net/packet/af_packet.c:276\n packet_snd net/packet/af_packet.c:3081 [inline]\n packet_sendmsg+0x8bb0/0x9ef0 net/packet/af_packet.c:3113\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg+0x30f/0x380 net/socket.c:745\n __sys_sendto+0x685/0x830 net/socket.c:2191\n __do_sys_sendto net/socket.c:2203 [inline]\n __se_sys_sendto net/socket.c:2199 [inline]\n __x64_sys_sendto+0x125/0x1d0 net/socket.c:2199\n do_syscall_64+0xd5/0x1f0\n entry_SYSCALL_64_after_hwframe+0x6d/0x75\n\nUninit was created at:\n slab_post_alloc_hook mm/slub.c:3804 [inline]\n slab_alloc_node mm/slub.c:3845 [inline]\n kmem_cache_alloc_node+0x613/0xc50 mm/slub.c:3888\n kmalloc_reserve+0x13d/0x4a0 net/core/skbuff.c:577\n __alloc_skb+0x35b/0x7a0 net/core/skbuff.c:668\n alloc_skb include/linux/skbuff.h:1318 [inline]\n alloc_skb_with_frags+0xc8/0xbf0 net/core/skbuff.c:6504\n sock_alloc_send_pskb+0xa81/0xbf0 net/core/sock.c:2795\n packet_alloc_skb net/packet/af_packet.c:2930 [inline]\n packet_snd net/packet/af_packet.c:3024 [inline]\n packet_sendmsg+0x722d/0x9ef0 net/packet/af_packet.c:3113\n sock_sendmsg_nosec net/socket.c:730 [inline]\n __sock_sendmsg+0x30f/0x380 net/socket.c:745\n __sys_sendto+0x685/0x830 net/socket.c:2191\n __do_sys_sendto net/socket.c:2203 [inline]\n __se_sys_sendto net/socket.c:2199 [inline]\n __x64_sys_sendto+0x125/0x1d0 net/socket.c:2199\n do_syscall_64+0xd5/0x1f0\n entry_SYSCALL_64_after_hwframe+0x6d/0x75\n\nCPU: 0 PID: 5033 Comm: syz-executor346 Not tainted 6.9.0-rc1-syzkaller-00005-g928a87efa423 #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 02/29/2024"
