According to the report, the Unisoc Tiger T700 chip, which powers the Motorola Moto G20, E30, and E40 smartphones, has been found to have a vulnerability when the cellular modem attempts to connect to an LTE network. The chip, named Unisoc T700 chip is used in three Motorola devices from last year – Moto G20, Moto E30, and the Moto E40 chipset. Checkpoint notified Unisoc last month and the company, evaluating the flaw to be at a critical risk of 9.4 out of 10, has patched the vulnerability.

“In this study, we looked at the UNISOC baseband as an attack target for the first time. We scanned NAS message handlers within a short period of time and found a vulnerability which can be used to disrupt the device’s radio communication through a malformed packet. A hacker or a military unit can leverage such a vulnerability to neutralize communications in a specific location,” Checkpoint Research said in its report.

Chip-level vulnerabilities of varying severity are found all the time and get passed up the chain of repair all the time. This is just a reminder that you don’t have to be scared of buying a phone with a Unisoc chip just on the fact that you’ve got a Unisoc chip — the company seems to be on the ball with fixing mistakes. But definitely make sure your device’s manufacturer is on that same ball.
