Overview

CVE-2024-53126 is a high-severity vulnerability. It was published on December 4, 2024 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. 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:

vdpa: solidrun: Fix UB bug with devres

In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to

pcim_iomap_regions() is placed on the stack. Neither

pcim_iomap_regions() nor the functions it calls copy that string.

Should the string later ever be used, this, consequently, causes

undefined behavior since the stack frame will by then have disappeared.

Fix the bug by allocating the strings on the heap through

devm_kasprintf().

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.
