Overview

CVE-2023-52507 is a high-severity vulnerability. It was published on March 2, 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:

nfc: nci: assert requested protocol is valid

The protocol is used in a bit mask to determine if the protocol is

supported. Assert the provided protocol is less than the maximum

defined so it doesn't potentially perform a shift-out-of-bounds and

provide a clearer error for undefined protocols vs unsupported ones.

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.
