Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: typec: altmodes/displayport: do not index invalid pin_assignments<br /> <br /> A poorly implemented DisplayPort Alt Mode port partner can indicate<br /> that its pin assignment capabilities are greater than the maximum<br /> value, DP_PIN_ASSIGN_F. In this case, calls to pin_assignment_show<br /> will cause a BRK exception due to an out of bounds array access.<br /> <br /> Prevent for loop in pin_assignment_show from accessing<br /> invalid values in pin_assignments by adding DP_PIN_ASSIGN_MAX<br /> value in typec_dp.h and using i
