Overview

CVE-2024-26723 is a high-severity vulnerability. It was published on April 3, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

lan966x: Fix crash when adding interface under a lag

There is a crash when adding one of the lan966x interfaces under a lag

interface. The issue can be reproduced like this:

ip link add name bond0 type bond miimon 100 mode balance-xor

ip link set dev eth0 master bond0

The reason is because when adding a interface under the lag it would go

through all the ports and try to figure out which other ports are under

that lag interface. And the issue is that lan966x can have ports that are

NULL pointer as they are not probed. So then iterating over these ports

it would just crash as they are NULL pointers.

The fix consists in actually checking for NULL pointers before accessing

something from the ports. Like we do in other places.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
