Kaspersky researchers conducted a security assessment of a modern System-on-Chip (SoC), Unisoc UIS7862A, which features an integrated 2G/3G/4G modem. This SoC can be found in various mobile devices by multiple vendors or, more interestingly, in the head units of modern Chinese vehicles, which are becoming increasingly common on the roads.
The head unit is one of a car’s key components, and a breach of its information security poses a threat to road safety, as well as the confidentiality of user data. During research, Kaspersky identified several critical vulnerabilities at various levels of the Unisoc UIS7862A modem’s cellular protocol stack. This article discusses a stack-based buffer overflow vulnerability in the 3G RLC protocol implementation (CVE-2024-39432).
