Name of the Vulnerable Software and Affected Versions TrustZone kernel on Motorola devices with Android 4.1.2

Description The issue allows local users to unlock the bootloader by using kernel mode to perform crafted 0x9 and 0x2 SMC operations, due to the lack of verification of the association between a certain physical-address argument and a memory region.

Recommendations For the affected Motorola devices with Android 4.1.2, consider restricting access to kernel mode operations until a patch is available. As a temporary workaround, avoid using the crafted SMC operations 0x9 and 0x2 to prevent potential exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
