Summary
usb: typec: fix potential out of bounds in ucsi_ccg_update_set_new_cam_cmd()
Details

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: fix potential out of bounds in ucsiccgupdatesetnewcamcmd()

The "*cmd" variable can be controlled by the user via debugfs. That means "newcam" can be as high as 255 while the size of the uc->updated[] array is UCSIMAX_ALTMODES (30).

The call tree is: ucsicmd() // val comes from simpleattrwritexsigned() -> ucsisendcommand() -> ucsisendcommandcommon() -> ucsiruncommand() // calls ucsi->ops->synccontrol() -> ucsiccgsync_control()
