In Preloader XFLASH, there is a possible escalation of privilege due to an improper certificate validation. This could lead to local escalation of privilege for an attacker who has physical access to the device with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06160806; Issue ID: ALPS06160806.
