Overview

CVE-2024-50274 is a high-severity vulnerability. It was published on November 19, 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:

idpf: avoid vport access in idpf_get_link_ksettings

When the device control plane is removed or the platform

running device control plane is rebooted, a reset is detected

on the driver. On driver reset, it releases the resources and

waits for the reset to complete. If the reset fails, it takes

the error path and releases the vport lock. At this time if the

monitoring tools tries to access link settings, it call traces

for accessing released vport pointer.

To avoid it, move link_speed_mbps to netdev_priv structure

which removes the dependency on vport pointer and the vport lock

in idpf_get_link_ksettings. Also use netif_carrier_ok()

to check the link status and adjust the offsetof to use link_up

instead of link_speed_mbps.

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.
