Overview

CVE-2024-39464 is a medium-severity vulnerability affecting linux linux_kernel. It was published on June 25, 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:

media: v4l: async: Fix notifier list entry init

struct v4l2_async_notifier has several list_head members, but only

waiting_list and done_list are initialized. notifier_entry was kept

'zeroed' leading to an uninitialized list_head.

This results in a NULL-pointer dereference if csi2_async_register() fails,

e.g. node for remote endpoint is disabled, and returns -ENOTCONN.

The following calls to v4l2_async_nf_unregister() results in a NULL

pointer dereference.

Add the missing list head initializer.

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.
