Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.6.61
Description:
A vulnerability in the Linux kernel has been resolved, specifically in the phy: qcom: qmp-usb module. The issue was caused by a commit that removed the initialisation of the platform device driver data, despite it still being used in the runtime PM callbacks. This led to a NULL-pointer dereference on runtime suspend. The vulnerability is resolved by restoring the driver data initialisation at probe. It is noted that runtime PM is not commonly used and needs to be enabled manually through sysfs with this driver.
Recommendations:
For Linux kernel versions prior to 6.6.61, update to version 6.6.61 or later to resolve the issue. As a temporary workaround, consider disabling runtime PM through sysfs to minimize the risk of exploitation.
