Overview

CVE-2024-41032 is a high-severity vulnerability. It was published on July 29, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, 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:

mm: vmalloc: check if a hash-index is in cpu_possible_mask

The problem is that there are systems where cpu_possible_mask has gaps

between set CPUs, for example SPARC. In this scenario addr_to_vb_xa()

hash function can return an index which accesses to not-possible and not

setup CPU area using per_cpu() macro. This results in an oops on SPARC.

A per-cpu vmap_block_queue is also used as hash table, incorrectly

assuming the cpu_possible_mask has no gaps. Fix it by adjusting an index

to a next possible CPU.

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.

How can CyberStrike help with CVE-2024-41032?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2024-41032 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
