Recently, cybersecurity firm Check Point Research announced a new vulnerability in the baseband processor of UNISOC’s chipsets. The vulnerability was discovered by Check Point Research during reverse engineering of the LTE protocol stack on the UNISOC T700 chip inside the Motorola Moto G20 phone. The vulnerability affects the network modem that is part of the chip and is directly responsible for network connectivity. This means that an attacker would be able to use the vulnerability to send corrupted network packets to the user, thereby disabling or interrupting the device’s network connection. At present, Check Point Research has submitted the discovered vulnerabilities to Unisplendour Zhanrui, and Unisplendour Zhanrui has officially confirmed the existence of the vulnerability and classified it as a 9.4-level serious vulnerability. In this regard, Ziguang Zhanrui has promised to patch the problem, and Google has confirmed the vulnerability, and said that the patch for it is expected to be fixed in the next Android security patch. .
