CVE-2023-48404Network attack vector

Remote information disclosure via missing bounds check

Published Dec 8, 2023 · Updated Aug 2, 2024

Out-of-bounds read in Google Android's exynos-ril component allows remote attackers to disclose memory via a crafted input. ProtocolMiscCarrierConfigSimInfoIndAdapter in protocolmiscadapter.cpp reads beyond a buffer because it fails to validate input bounds. Exploitation requires no privileges or user interaction, and the documented consequence is information disclosure without integrity or availability impact.
