Samsung LTE RRC buffer overflow vulnerability

Samsung LTE RRC is a protocol in Samsung (Samsung) mobile devices. The RRC word layer has many functions, including the broadcast of non-access layer (NAS) related system information, the broadcast of access layer (AS) related system information, paging, and the establishment, maintenance, and release of RRC connections between the UE and E-UTRAN.Samsung LTE RRC is vulnerable to a buffer overflow vulnerability that stems from a lack of boundary checking in the Exynos CP chipset, which can be exploited by attackers to write and execute code in memory.
