CVE-2023-48397Network attack vector

Remote information disclosure via missing bounds check

Published Dec 8, 2023 · Updated Aug 2, 2024

Information disclosure in Google Android kernel allows remote attackers to read memory via a missing bounds check in protocolcalladapter.cpp. The Init routine processes protocol data without validating a required bound, enabling an out-of-bounds read in the exynos-ril component. Exploitation requires System execution privileges but no user interaction, and the documented impact is limited to disclosure of information.
