CVE-2024-53203: usb: typec: fix potential array underflow in ucsi_ccg_sync_control()
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: fix potential array underflow in ucsiccgsynccontrol()
The "command" variable can be controlled by the user via debugfs. The worry is that if conindex is zero then "&uc->ucsi->connector[conindex - 1]" would be an array underflow.
