CVE-2020-0101Public exploit

Local memory disclosure via unchecked Parcel reads

Published May 14, 2020 · Updated Aug 4, 2024

Information disclosure in Android 8.0, 8.1, 9, and 10 allows local users with System privileges to read uninitialized process data. BnCrypto::onTransact in drm/libmediadrm/ICrypto.cpp accepts short CREATE_PLUGIN Parcel reads without checking errors, then passes incompletely initialized UUID or opaque buffers to createPlugin. Exploitation requires local System execution privileges and no user interaction; exposure is limited to memory disclosure from the privileged media process.
