The\nport altmode array is UCSI_MAX_ALTMODES elements long. If the PPM\nreturns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and\nnot equal to 0xff, the kernel may crash with an array index OOB error.\n\nUpdate the UCSI displayport driver to verify the current cam is less\nthan UCSI_MAX_ALTMODES before accessing the port altmode array.",
