Overview

CVE-2024-58084 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:

firmware: qcom: scm: Fix missing read barrier in qcom_scm_get_tzmem_pool()

Commit 2e4955167ec5 ("firmware: qcom: scm: Fix __scm and waitq

completion variable initialization") introduced a write barrier in probe

function to store global '__scm' variable. We all known barriers are

paired (see memory-barriers.txt: "Note that write barriers should

normally be paired with read or address-dependency barriers"), therefore

accessing it from concurrent contexts requires read barrier. Previous

commit added such barrier in qcom_scm_is_available(), so let's use that

directly.

Lack of this read barrier can result in fetching stale '__scm' variable

value, NULL, and dereferencing it.

Note that barrier in qcom_scm_is_available() satisfies here the control

dependency.

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-2024-58084?

CyberStrike is an open-source, AI-augmented pentesting engine.
