Samsung Exynos Processors Out-of-Bounds Access Vulnerability via Malformed RRC Packets

Vulnerability

A vulnerability exists in various Samsung mobile and wearable processors, including Exynos 980, 990, 850, 1080, 2100, 1280, 2200, 1330, 1380, 1480, 2400, 9110, W920, W930, W1000, as well as Modem 5123, Modem 5300, and Modem 5400.
