Critical flaw found inside the UNISOC smartphone chip.

Check Point Research has identified what it is calling a critical security vulnerability in UNISOC's smartphone chip, which is responsible for cellular communication in 11% of the world's smartphones.

CPR found the vulnerability while conducting an analysis of the UNISOC baseband to find a way to remotely attack UNISOC devices, the company said in a blog post.

UNISOC, MediaTek and Qualcomm are the top three chip makers for Android devices, according to CPR. In the past three years, CPR has researched Qualcomm's TrustZone, DSP and radio modem processors, as well as MediaTek's TrustZone DSP. Even though UNISOC has been on the market for a long time, the chip firmware used in Android mobile phones has not been studied extensively, a CPR spokesperson said Wednesday.

"The smartphone modem is a prime target for hackers as it can be easily reached remotely through SMS or a radio packet," UNISOC said.
