CVE-2024-50240 Details
Description
In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usb: 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, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. 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 this driver.
A vulnerability in the Linux kernel's QCOM QMP-USB driver can lead to a NULL pointer dereference during runtime suspension. This issue arises because a recent commit removed crucial platform device driver initialization data, which is still needed for runtime power management callbacks. Although the driver currently requires manual activation through sysfs, the vulnerability could cause a crash when runtime suspend is engaged.
Users can upgrade to the patched version of the Linux kernel available in the Linux kernel stable tree.
