Description
In the Linux kernel, the following vulnerability has been resolved:
USB: dwc2: shut down wakeup timer before freeing HCD state
dwc2_wakeup_detected() accesses the DWC2 host state and can rearm the
wakeup timer. dwc2_hcd_free() currently deletes the timer only after
freeing host-owned state, and timer_delete() does not synchronize a
callback or prevent it from being queued again.
Stop and shut down the timer in dwc2_hcd_release(), before the HCD
resources are freed. This covers both the HCD initialization error path
and normal HCD removal.
