Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> phy: qcom: qmp-usb: fix NULL-deref on runtime suspend<br /> <br /> Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation")<br /> removed most users of the platform device driver data, but mistakenly<br /> also removed the initialisation despite the data still being used in the<br /> runtime PM callbacks.<br /> <br /> Restore the driver data initialisation at probe to avoid a NULL-pointer<br /> dereference on runtime suspend.<br /> <br /> Apparently no one uses runtime PM, which currently needs to be enabled<br /> manually through sysfs, with this driver.
