Overview

CVE-2024-53075 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 19, 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:

riscv: Prevent a bad reference count on CPU nodes

When populating cache leaves we previously fetched the CPU device node

at the very beginning. But when ACPI is enabled we go through a

specific branch which returns early and does not call 'of_node_put' for

the node that was acquired.

Since we are not using a CPU device node for the ACPI code anyways, we

can simply move the initialization of it just passed the ACPI block, and

we are guaranteed to have an 'of_node_put' call for the acquired node.

This prevents a bad reference count of the CPU device node.

Moreover, the previous function did not check for errors when acquiring

the device node, so a return -ENOENT has been added for that case.

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.
