CVE-2020-0049Network attack vector

Remote information disclosure via uninitialized buffer data

Published Mar 10, 2020 · Updated Aug 4, 2024

Information disclosure in Android 10 allows remote attackers to read uninitialized data through the StreamingSource.cpp onReadBuffer() path. The onReadBuffer() routine returns data that was not initialized before being exposed, allowing contents of memory to enter a media stream. User interaction is required to trigger exploitation, and the reported consequence is remote confidentiality loss without integrity or availability impact.
