Overview

CVE-2024-44970 is a critical-severity vulnerability. It was published on September 4, 2024 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink

When all the strides in a WQE have been consumed, the WQE is unlinked

from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible

to receive CQEs with 0 consumed strides for the same WQE even after the

WQE is fully consumed and unlinked. This triggers an additional unlink

for the same wqe which corrupts the linked list.

Fix this scenario by accepting 0 sized consumed strides without

unlinking the WQE again.

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.
