Samsung Exynos Processors Heap-Based Out-of-Bounds Write Vulnerability in GPRS Protocol

Vulnerability

A heap-based out-of-bounds write vulnerability has been identified in the GPRS protocol implementation of various Samsung mobile processors, wearable processors, and modems. This vulnerability arises from a mismatch between the actual length of the payload and the length declared within the payload, leading to potential memory corruption.

Impact

Exploitation of this vulnerability could result in a heap-based out-of-bounds write, allowing for memory corruption that could be exploited to execute arbitrary code or cause a denial-of-service condition.
