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