Overview

CVE-2024-58000 is a medium-severity vulnerability. It was published on February 27, 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:

io_uring: prevent reg-wait speculations

With *ENTER_EXT_ARG_REG instead of passing a user pointer with arguments

for the waiting loop the user can specify an offset into a pre-mapped

region of memory, in which case the

[offset, offset + sizeof(io_uring_reg_wait)) will be intepreted as the

argument.

As we address a kernel array using a user given index, it'd be a subject

to speculation type of exploits. Use array_index_nospec() to prevent

that. Make sure to pass not the full region size but truncate by the

maximum offset allowed considering the structure size.

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.
