In the Linux kernel, the following vulnerability has been resolved: bonding: do not assume skb mac_header is set Drivers must not assume in their ndo_start_xmit() that skbs have their mac_header set. skb->data is all what is needed. bonding seems to be one of the last offender as caught by syzbot: WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 skb_mac_offset include/linux/skbuff.h:2913 [inline] WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 bond_xmit_hash drivers/net/bonding/bond_main.c:4170 [inline] WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 bond_xmit_3ad_xor_slave_get drivers/net/bonding/bond_main.c:5149 [inline] WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 bond_3ad_xor_xmit drivers/net/bonding/bond_main.c:5186 [inline] WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 __bond_start_xmit drivers/net/bonding/bond_main.c:5442 [inline] WARNING: CPU: 1 PID: 12155 at include/linux/skbuff.h:2907 bond_start_xmit+0x14ab/0x19d0 drivers/net/bonding/bond_main.c:5470 Modules linked in: CPU: 1 PID: 12155 Comm: syz-executor.3 Not tainted 6.1.30-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/25/2023 RIP: 0010:skb_mac_header include/linux/skbuff.h:2907 [inline] RIP: 0010:skb_mac_offset include/linux/skbuff.h:2913 [inline] RIP: 0010:bond_xmit_hash drivers/net/bonding/bond_main.c:4170 [inline] RIP: 0010:bond_xmit_3ad_xor_slave_get drivers/net/bonding/bond_main.c:5149 [inline] RIP: 0010:bond_3ad_xor_xmit drivers/net/bonding/bond_main.c:5186 [inline] RIP: 0010:__bond_start_xmit drivers/net/bonding/bond_main.c:5442 [inline] RIP: 0010:bond_start_xmit+0x14ab/0x19d0 drivers/net/bonding/bond_main.c:5470 Code: 8b 7c 24 30 e8 76 dd 1a 01 48 85 c0 74 0d 48 89 c3 e8 29 67 2e fe e9 15 ef ff ff e8 1f 67 2e fe e9 10 ef ff ff e8 15 67 2e fe 0b e9 45 f8 ff ff e8 09 67 2e fe e9 dc fa ff ff e8 ff 66 2e fe RSP: 0018:ffffc90002fff6e0 EFLAGS: 00010283 RAX: ffffffff835874db RBX: 000000000000ffff
