In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: cancel vdm and state machine hrtimer when unregister tcpm port
A pending hrtimer may expire after the kthread_worker of tcpm port is destroyed, see below kernel dump when do module unload, fix it by cancel the 2 hrtimers.
