Descriptions
In the Linux kernel, the following vulnerability has been resolved:
netkit: Assign missing bpf_net_context
During the introduction of struct bpf_net_context handling for
XDP-redirect, the netkit driver has been missed, which also requires it
because NETKIT_REDIRECT invokes skb_do_redirect() which is accessing the
per-CPU variables. Otherwise we see the following crash:
BUG: kernel NULL pointer dereference, address: 0000000000000038
bpf_redirect()
netkit_xmit()
dev_hard_start_xmit()
Set the bpf_net_context before invoking netkit_xmit() program within the
netkit driver.
