Overview

CVE-2023-52754 is a medium-severity vulnerability. It was published on May 21, 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:

media: imon: fix access to invalid resource for the second interface

imon driver probes two USB interfaces, and at the probe of the second

interface, the driver assumes blindly that the first interface got

bound with the same imon driver. It's usually true, but it's still

possible that the first interface is bound with another driver via a

malformed descriptor. Then it may lead to a memory corruption, as

spotted by syzkaller; imon driver accesses the data from drvdata as

struct imon_context object although it's a completely different one

that was assigned by another driver.

This patch adds a sanity check -- whether the first interface is

really bound with the imon driver or not -- for avoiding the problem

above at the probe time.

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.
