Overview

CVE-2024-58085 is a medium-severity vulnerability. It was published on March 6, 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:

tomoyo: don't emit warning in tomoyo_write_control()

syzbot is reporting too large allocation warning at tomoyo_write_control(),

for one can write a very very long line without new line character. To fix

this warning, I use __GFP_NOWARN rather than checking for KMALLOC_MAX_SIZE,

for practically a valid line should be always shorter than 32KB where the

"too small to fail" memory-allocation rule applies.

One might try to write a valid line that is longer than 32KB, but such

request will likely fail with -ENOMEM. Therefore, I feel that separately

returning -EINVAL when a line is longer than KMALLOC_MAX_SIZE is redundant.

There is no need to distinguish over-32KB and over-KMALLOC_MAX_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.

How can CyberStrike help with CVE-2024-58085?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2024-58085 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.
