Heap-Based Buffer Overflow in Samsung Mobile Chipset and Baseband Modem

CVE-2023-26073

Summary

A vulnerability has been identified in Samsung's Exynos mobile chipset and baseband modem systems, where a heap-based buffer overflow may occur. This issue arises from inadequate parameter validation during the decoding of the extended emergency number list in the 5G MM message codec, potentially leading to data corruption or other unforeseen behavior. The affected products include several Exynos chipsets ranging from the Exynos 850 to the Exynos 2200, as well as multiple modem variants. This flaw emphasizes the importance of stringent validation protocols in mobile communication systems to safeguard against exploitation.
