CVE-2023-35656Network attack vector

Remote information disclosure via unchecked RIL bounds

Published Oct 18, 2023 · Updated Sep 13, 2024

Out-of-bounds reads in Google Android's Exynos RIL allow remote attackers to disclose memory without privileges or interaction. Multiple functions in protocolembmsadapter.cpp read beyond buffer boundaries because required bounds checks are missing for remotely supplied protocol data. The attack requires no privileges or user interaction and has no reported integrity or availability effect.
