Deskripsi CVE
In the Linux kernel, the following vulnerability has been resolved:
phy: qcom: qmp-usb: Fix possible NULL-deref on early runtime suspend
There is a small window where the runtime suspend callback may run
after pm_runtime_enable() and before pm_runtime_forbid(). In this
case, a crash occurs because runtime suspend/resume dereferences
qmp->phy pointer, which is not yet initialized:
`if (!qmp->phy->init_count) {`
This can also happen if user re-enables runtime-pm via the sysfs
attribute before qmp phy is initialized.
Similarly to other qcom phy drivers, introduce a qmp->phy_initialized
variable that can be used to avoid relying on the possibly uninitialized
phy pointer.
