CVE-2024-50238
5.5 · MEDIUMOverview
CVE-2024-50238 is a medium-severity vulnerability affecting linux linux_kernel. 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 and patches from linux. Update linux_kernel to the latest patched version. 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.
