Overview

CVE-2024-47708 is a medium-severity vulnerability affecting linux linux_kernel. It was published on October 21, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
