CVE-2026-89470

power: supply: cros_usbpd: Limit port counts to EC_USB_PD_MAX_PORTS

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

power: supply: cros_usbpd: Limit port counts to EC_USB_PD_MAX_PORTS

Currently the cros_usbpd-charger driver probe iterates based on raw
charger port count returned by the embedded controller. The only check
is against the number of USB PD ports which the embedded controller
also defines. A malicious embedded controller could return an inaccurate
port count (up to 255) resulting in an out of bounds write and
subsequent memory corruption.

Update helper functions in cros_usbpd-charger to limit port counts to
EC_USB_PD_MAX_PORTS.
