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