Overview

CVE-2024-27003 is a medium-severity vulnerability. It was published on May 1, 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:

clk: Get runtime PM before walking tree for clk_summary

Similar to the previous commit, we should make sure that all devices are

runtime resumed before printing the clk_summary through debugfs. Failure

to do so would result in a deadlock if the thread is resuming a device

to print clk state and that device is also runtime resuming in another

thread, e.g the screen is turning on and the display driver is starting

up. We remove the calls to clk_pm_runtime_{get,put}() in this path

because they're superfluous now that we know the devices are runtime

resumed. This also squashes a bug where the return value of

clk_pm_runtime_get() wasn't checked, leading to an RPM count underflow

on error paths.

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.
