-Subject: [PATCH] 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.
-
-Fixes: 8913336a7e8d ("packet: add PACKET_RESERVE sockopt")
