Overview

CVE-2024-38594 is a medium-severity vulnerability. It was published on June 19, 2024 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:

net: stmmac: move the EST lock to struct stmmac_priv

Reinitialize the whole EST structure would also reset the mutex

lock which is embedded in the EST structure, and then trigger

the following warning. To address this, move the lock to struct

stmmac_priv. We also need to reacquire the mutex lock when doing

this initialization.

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.
