Overview

CVE-2024-40968 is a medium-severity vulnerability. It was published on July 12, 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:

MIPS: Octeon: Add PCIe link status check

The standard PCIe configuration read-write interface is used to

access the configuration space of the peripheral PCIe devices

of the mips processor after the PCIe link surprise down, it can

generate kernel panic caused by "Data bus error". So it is

necessary to add PCIe link status check for system protection.

When the PCIe link is down or in training, assigning a value

of 0 to the configuration address can prevent read-write behavior

to the configuration space of peripheral PCIe devices, thereby

preventing kernel panic.

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.
