According to IT Home, cybersecurity research firm Check Point Research recently announced a new vulnerability it discovered in the baseband processor of the UNISOC Zhanrui chipset.
According to the investigative blog, the vulnerability affects network modems that are part of the chipset and are responsible for network connectivity. In theory, it could allow an attacker to send corrupted network packets and disable or disrupt the device’s network connectivity.
Check Point Research discovered the vulnerability by reverse engineering the LTE protocol stack implementation on the UNISOC T700 chip inside the Motorola Moto G20 phone (XT2128-2) with the January 2022 security patch installed.
It is understood that Check Point Research contacted the UNISOC team in May 2022 and disclosed these findings. Ziguang Zhanrui acknowledged the discovery and gave the vulnerability 9.4 (critical), promising to fix it.
Google has confirmed that the patch for this vulnerability will be part of the Android Security Bulletin, which means it is expected to be fixed in the next Android security patch.
