Overview

CVE-2024-42093 is a high-severity vulnerability. It was published on July 29, 2024 and has a CVSS 3.1 base score of 7.3 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.3, rated HIGH. 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/dpaa2: Avoid explicit cpumask var allocation on stack

For CONFIG_CPUMASK_OFFSTACK=y kernel, explicit allocation of cpumask

variable on stack is not recommended since it can cause potential stack

overflow.

Instead, kernel code should always use *cpumask_var API(s) to allocate

cpumask var in config-neutral way, leaving allocation strategy to

CONFIG_CPUMASK_OFFSTACK.

Use *cpumask_var API(s) to address it.

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.
