Overview

CVE-2024-57890 is a medium-severity vulnerability. It was published on January 15, 2025 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:

RDMA/uverbs: Prevent integer overflow issue

In the expression "cmd.wqe_size * cmd.wr_count", both variables are u32

values that come from the user so the multiplication can lead to integer

wrapping. Then we pass the result to uverbs_request_next_ptr() which also

could potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)"

multiplication can also overflow on 32bit systems although it's fine on

64bit systems.

This patch does two things. First, I've re-arranged the condition in

uverbs_request_next_ptr() so that the use controlled variable "len" is on

one side of the comparison by itself without any math. Then I've modified

all the callers to use size_mul() for the multiplications.

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-2024-57890?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2024-57890 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.
