Analysis shows that the skb has a valid ->head, but bogus ->data pointer. skb->data gets its bogus value via the neigh layer, which does: 1556 __skb_pull(skb, skb_network_offset(skb)); ... and the skb was already dodgy at this point: skb_network_offset(skb) returns a negative value due to an earlier overflow of skb->network_header (u16). __skb_pull thus "adjusts" skb->data by a huge offset, pointing outside skb->head area. Allow debug builds to splat when we try to pull/push more than INT_MAX bytes. After this, the syzkaller reproducer yields a more precise splat before the flow dissector attempts to read off skb->data memory: WARNING: CPU: 5 PID: 2313 at include/linux/skbuff.h:2653 neigh_connected_output+0x28e/0x400 ip_finish_output2+0xb25/0xed0 iptunnel_xmit+0x4ff/0x870 ipgre_xmit+0x78e/0xbb0 Signed-off-by: Florian Westphal Reviewed-by: Simon Horman Link: https://lore.kernel.org/r/20240216113700.23013-1-fw@strlen.de Signed-off-by: Paolo Abeni include/linux/skbuff.h | 6 ++++++ 1 file changed, 6 insertions(+) accumulated error probability: 0.00 culprit signature: fb9afd625176033853ab4fb395f0b3f3e084369a3a69b817bdb0013d3cbb3e39 parent signature: 7dd54d442c8d7442aa7110029d2700f5d088800c54761dbf0122e15da61b6f90 revisions tested: 23, total time: 9h5m5.271174472s (build: 4h27m13.845937859s, test: 4h21m16.055074311s) first bad commit: 219eee9c0d16f1b754a8b85275854ab17df0850a net: skbuff: add overflow debug check to pull/push helpers recipients (to): ["fw@strlen.de" "horms@kernel.org" "pabeni@redhat.com"] recipients (cc): [] crash: WARNING in ip6gre_tunnel_xmit protocol 894f is buggy, dev ip6gretap0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 20054 at include/linux/skbuff.h:2723 pskb_may_pull_reason include/linux/skbuff.h:2723 [inline] WARNING: CPU: 0 PID: 20054 at include/linux/skbuff.h:2723 pskb_may_pull include/linux/skbuff.h:2739 [inline] WARNING: CPU: 0 PID: 20054 at include/linux/skbuff.h:2723 pskb_network_may_pull include/linux/skbuff.h:3054 [inline] WARNING: CPU: 0 PID: 20054 at include/linux/skbuff.h:2723 pskb_inet_may_pull include/net/ip_tunnels.h:361 [inline] WARNING: CPU: 0 PID: 20054 at include/linux/skbuff.h:2723 ip6gre_tunnel_xmit+0x49d/0x680 net/ipv6/ip6_gre.c:901 Modules linked in: CPU: 0 PID: 20054 Comm: syz-executor202 Not tainted 6.8.0-rc4-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/25/2024 RIP: 0010:pskb_may_pull_reason include/linux/skbuff.h:2723 [inline] RIP: 0010:pskb_may_pull include/linux/skbuff.h:2739 [inline] RIP: 0010:pskb_network_may_pull include/linux/skbuff.h:3054 [inline] RIP: 0010:pskb_inet_may_pull include/net/ip_tunnels.h:361 [inline] RIP: 0010:ip6gre_tunnel_xmit+0x49d/0x680 net/ipv6/ip6_gre.c:901 Code: 00 00 00 ba 04 00 00 00 e8 c0 68 ee ff 85 ed 0f 89 92 01 00 00 e9 56 01 00 00 31 ed 85 ed 0f 89 83 01 00 00 e9 47 01 00 00 90 <0f> 0b 90 e9 be fb ff ff 39 c1 0f 82 36 01 00 00 4c 89 e7 e8 eb c0 RSP: 0018:ffffc900031cbac0 EFLAGS: 00010286 RAX: 00000000ffffff5a RBX: ffff8881053e2601 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffff88810dfb3000 RDI: ffff8881053e2600 RBP: ffffffff832f25d0 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: ffffffff82ac6670 R12: ffff8881053e2600 R13: ffff8881053e2600 R14: ffff88810dfb3000 R15: ffff8881053e2000 FS: 000055555661f380(0000) GS:ffff88813bc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020003000 CR3: 000000010733e000 CR4: 00000000003506f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: __netdev_start_xmit include/linux/netdevice.h:4990 [inline] netdev_start_xmit include/linux/netdevice.h:5004 [inline] xmit_one net/core/dev.c:3530 [inline] dev_hard_start_xmit+0xdb/0x280 net/core/dev.c:3546 sch_direct_xmit+0xe5/0x290 net/sched/sch_generic.c:342 __dev_xmit_skb net/core/dev.c:3759 [inline] __dev_queue_xmit+0x753/0xdc0 net/core/dev.c:4300 packet_snd net/packet/af_packet.c:3081 [inline] packet_sendmsg+0x12a2/0x16f0 net/packet/af_packet.c:3113 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg+0x8e/0xb0 net/socket.c:745 __sys_sendto+0x23c/0x290 net/socket.c:2191 __do_sys_sendto net/socket.c:2203 [inline] __se_sys_sendto net/socket.c:2199 [inline] __x64_sys_sendto+0x21/0x30 net/socket.c:2199 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xe6/0x200 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x6f/0x77 RIP: 0033:0x7f576f195b69 Code: 28 00 00 00 75 05 48 83 c4 28 c3 e8 d1 19 00 00 90 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b8 ff ff ff f7 d8 64 89 01 48 RSP: 002b:00007fff96eda5d8 EFLAGS: 00000246 ORIG_RAX: 000000000000002c RAX: ffffffffffffffda RBX: 0000000000000003 RCX: 00007f576f195b69 RDX: 0000000000003287 RSI: 0000000020000080 RDI: 0000000000000003 RBP: 00000000000f4240 R08: 0000000000000000 R09: 00000000000002ff R10: 0000000004000002 R11: 0000000000000246 R12: 00007fff96eda640 R13: 000000000005ec1e R14: 00007fff96eda60c R15: 0000000000000003
