Overview

CVE-2024-56680 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 28, 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:

media: intel/ipu6: do not handle interrupts when device is disabled

Some IPU6 devices have shared interrupts. We need to handle properly

case when interrupt is triggered from other device on shared irq line

and IPU6 itself disabled. In such case we get 0xffffffff from

ISR_STATUS register and handle all irq's cases, for what we are not

not prepared and usually hang the whole system.

To avoid the issue use pm_runtime_get_if_active() to check if

the device is enabled and prevent suspending it when we handle irq

until the end of irq. Additionally use synchronize_irq() in suspend

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
