Overview

CVE-2024-56660 is a medium-severity vulnerability. It was published on December 27, 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:

net/mlx5: DR, prevent potential error pointer dereference

The dr_domain_add_vport_cap() function generally returns NULL on error

but sometimes we want it to return ERR_PTR(-EBUSY) so the caller can

retry. The problem here is that "ret" can be either -EBUSY or -ENOMEM

and if it's and -ENOMEM then the error pointer is propogated back and

eventually dereferenced in dr_ste_v0_build_src_gvmi_qpn_tag().

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.
