Published May 30, 2024 linux CWE-416 EPSS 0.20% (10th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-36932 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 30, 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:

thermal/debugfs: Prevent use-after-free from occurring after cdev removal

Since thermal_debug_cdev_remove() does not run under cdev->lock, it can

run in parallel with thermal_debug_cdev_state_update() and it may free

the struct thermal_debugfs object used by the latter after it has been

checked against NULL.

If that happens, thermal_debug_cdev_state_update() will access memory

that has been freed already causing the kernel to crash.

Address this by using cdev->lock in thermal_debug_cdev_remove() around

the cdev->debugfs value check (in case the same cdev is removed at the

same time in two different threads) and its reset to NULL.

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.
