Memory corruption via unauthenticated 2G heap overwrite
Published Jul 9, 2024 · Updated Nov 25, 2024
Heap out-of-bounds write in affected Samsung Exynos processors and modems allows remote attackers to corrupt memory via unauthenticated 2G traffic. The 2G baseband code writes beyond a heap buffer, but Samsung has not disclosed the parser, input field, or malformed message that triggers the write. Reachability requires 2G connectivity and no authentication or user interaction; the record does not establish whether corruption causes a crash, code execution, or another effect.
