Overview

CVE-2024-50238 is a medium-severity vulnerability. It was published on November 9, 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:

phy: qcom: qmp-usbc: fix NULL-deref on runtime suspend

Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation")

removed most users of the platform device driver data from the

qcom-qmp-usb driver, but mistakenly also removed the initialisation

despite the data still being used in the runtime PM callbacks. This bug

was later reproduced when the driver was copied to create the qmp-usbc

driver.

Restore the driver data initialisation at probe to avoid a NULL-pointer

dereference on runtime suspend.

Apparently no one uses runtime PM, which currently needs to be enabled

manually through sysfs, with these drivers.

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.
