CVSS: 9.8EPSS: 0%CPEs: 18EXPL: 0CVE-2023-26075 – Shannon Baseband NrmmMsgCodec Intra-Object Overflow
https://notcve.org/view.php?id=CVE-2023-26075
An issue was discovered in Samsung Mobile Chipset and Baseband Modem Chipset for Exynos 850, Exynos 980, Exynos 1080, Exynos 1280, Exynos 2200, Exynos Modem 5123, Exynos Modem 5300, and Exynos Auto T5123. An intra-object overflow in the 5G MM message codec can occur due to insufficient parameter validation when decoding the Service Area List. There is an intra-object overflow in Shannon Baseband, inside the 5G MM protocol implementation (NrmmMsgCodec as it is called in Shannon according to debug strings), specifically when handling the Service Area List message (IEI = 0x27). • http://packetstormsecurity.com/files/171387/Shannon-Baseband-NrmmMsgCodec-Intra-Object-Overflow.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2398 https://googleprojectzero.blogspot.com/2023/03/multiple-internet-to-baseband-remote-rce.html https://semiconductor.samsung.com/processor/mobile-processor https://semiconductor.samsung.com/processor/modem https://semiconductor.samsung.com/support/quality-support/product-security-updates • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
