CVE-2024-26747

4.4 · MEDIUM
Published Apr 3, 2024 linux CWE-476 EPSS 0.24% (15th pctl)

Overview

CVE-2024-26747 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 3, 2024 and has a CVSS 3.1 base score of 4.4 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.4, 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:

usb: roles: fix NULL pointer issue when put module's reference

In current design, usb role class driver will get usb_role_switch parent's

module reference after the user get usb_role_switch device and put the

reference after the user put the usb_role_switch device. However, the

parent device of usb_role_switch may be removed before the user put the

usb_role_switch. If so, then, NULL pointer issue will be met when the user

put the parent module's reference.

This will save the module pointer in structure of usb_role_switch. Then,

we don't need to find module by iterating long relations.

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.
