Overview

CVE-2023-54041 is a known-severity vulnerability. It was published on December 24, 2025.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

io_uring: fix memory leak when removing provided buffers

When removing provided buffers, io_buffer structs are not being disposed

of, leading to a memory leak. They can't be freed individually, because

they are allocated in page-sized groups. They need to be added to some

free list instead, such as io_buffers_cache. All callers already hold

the lock protecting it, apart from when destroying buffers, so had to

extend the lock there.

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-2023-54041?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2023-54041 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.
