CVE-2024-27047

5.5 · MEDIUM
Published May 1, 2024 linux CWE-476 EPSS 0.28% (20th pctl)

Overview

CVE-2024-27047 is a medium-severity vulnerability affecting linux linux_kernel. 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:

net: phy: fix phy_get_internal_delay accessing an empty array

The phy_get_internal_delay function could try to access to an empty

array in the case that the driver is calling phy_get_internal_delay

without defining delay_values and rx-internal-delay-ps or

tx-internal-delay-ps is defined to 0 in the device-tree.

This will lead to "unable to handle kernel NULL pointer dereference at

virtual address 0". To avoid this kernel oops, the test should be delay

>= 0. As there is already delay < 0 test just before, the test could

only be size == 0.

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.
