Overview

CVE-2024-40965 is a medium-severity vulnerability. It was published on July 12, 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:

i2c: lpi2c: Avoid calling clk_get_rate during transfer

Instead of repeatedly calling clk_get_rate for each transfer, lock

the clock rate and cache the value.

A deadlock has been observed while adding tlv320aic32x4 audio codec to

the system. When this clock provider adds its clock, the clk mutex is

locked already, it needs to access i2c, which in return needs the mutex

for clk_get_rate as well.

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.
