Or Cohen acf69c9462 net/packet: fix overflow in tpacket_rcv ... Using tp_reserve to calculate netoff can overflow as tp_reserve is unsigned int and netoff is unsigned short. This may lead to macoff receving a smaller value then sizeof(struct virtio_net_hdr), and if po->has_vnet_hdr is set, an out-of-bounds write will occur when calling virtio_net_hdr_from_skb. The bug is fixed by converting netoff to unsigned int and checking if it exceeds USHRT_MAX. This addresses CVE-2020-14386 Fixes: 8913336a7e ("packet: add PACKET_RESERVE sockopt") Signed-off-by: Or Cohen <orcohen@paloaltonetworks.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2020-09-04 11:56:02 -07:00
