Overview

CVE-2024-26963 is a medium-severity vulnerability. It was published on May 1, 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:

usb: dwc3-am62: fix module unload/reload behavior

As runtime PM is enabled, the module can be runtime

suspended when .remove() is called.

Do a pm_runtime_get_sync() to make sure module is active

before doing any register operations.

Doing a pm_runtime_put_sync() should disable the refclk

so no need to disable it again.

Fixes the below warning at module removel.

[ 39.705310] ------------[ cut here ]------------

[ 39.710004] clk:162:3 already disabled

[ 39.713941] WARNING: CPU: 0 PID: 921 at drivers/clk/clk.c:1090 clk_core_disable+0xb0/0xb8

We called of_platform_populate() in .probe() so call the

cleanup function of_platform_depopulate() in .remove().

Get rid of the now unnnecessary dwc3_ti_remove_core().

Without this, module re-load doesn't work properly.

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.
