CVSS: 9.8EPSS: 0%CPEs: 6EXPL: 0CVE-2023-28613 – Shannon Baseband Integer Overflow
https://notcve.org/view.php?id=CVE-2023-28613
An issue was discovered in Samsung Exynos Mobile Processor and Baseband Modem Processor for Exynos 1280, Exynos 2200, and Exynos Modem 5300. An integer overflow in IPv4 fragment handling can occur due to insufficient parameter validation when reassembling these fragments. There is an integer overflow in Shannon Baseband leading to a heap buffer overflow when reassembling IPv4 fragments. According to the debug strings, this corresponding functionality is implemented in SmdtIp4Rx::ProcessFragments function and its callees. • http://packetstormsecurity.com/files/172177/Shannon-Baseband-Integer-Overflow.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-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2023-26072
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. A heap-based buffer overflow in the 5G MM message codec can occur due to insufficient parameter validation when decoding the Emergency number list. There is a heap buffer 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 "Emergency number list" message (IEI = 0x34). • http://packetstormsecurity.com/files/171378/Shannon-Baseband-NrmmMsgCodec-Emergency-Number-List-Heap-Buffer-Overflow.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2395 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-787: Out-of-bounds Write •
