CVE-2020-0146

Local information disclosure via unchecked Bluetooth event length

Published Jun 11, 2020 · Updated Aug 4, 2024

Information disclosure in Google Cloud Android 10 allows local users to read memory through a malformed Bluetooth hardware-error event. The btu_hcif_hardware_error_evt function in btu_hcif.cc reads event data without checking its bounds, exposing bytes beyond the valid buffer. Exploitation requires compromised device firmware running with System execution privileges and needs no user interaction; impact is limited to local confidentiality.
