CVE-2024-47708
MediumIn 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.
