Overview

CVE-2024-50260 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 9, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, 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:

sock_map: fix a NULL pointer dereference in sock_map_link_update_prog()

The following race condition could trigger a NULL pointer dereference:

sock_map_link_detach(): sock_map_link_update_prog():

mutex_lock(&sockmap_mutex);

...

sockmap_link->map = NULL;

mutex_unlock(&sockmap_mutex);

mutex_lock(&sockmap_mutex);

...

sock_map_prog_link_lookup(sockmap_link->map);

mutex_unlock(&sockmap_mutex);

Fix it by adding a NULL pointer check. In this specific case, it makes

no sense to update a link which is being released.

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.
