Overview

CVE-2024-46717 is a critical-severity vulnerability. It was published on September 18, 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 incorrect page release

Under the following conditions:

1) No skb created yet

2) header_size == 0 (no SHAMPO header)

3) header_index + 1 % MLX5E_SHAMPO_WQ_HEADER_PER_PAGE == 0 (this is the

last page fragment of a SHAMPO header page)

a new skb is formed with a page that is NOT a SHAMPO header page (it

is a regular data page). Further down in the same function

(mlx5e_handle_rx_cqe_mpwrq_shampo()), a SHAMPO header page from

header_index is released. This is wrong and it leads to SHAMPO header

pages being released more than once.

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.
