CVE-2020-0008

Local memory disclosure via dangling Bluetooth pointer

Published Jan 8, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Android 8.0 through 10 allows local users to disclose process memory through a Bluetooth callback race. LowEnergyClient::MtuChangedCallback stores a c_str() pointer from the temporary string returned by BtAddrString(), leaving a dangling pointer that can be read after the temporary is destroyed. Exploitation requires local low-privileged access and no user interaction; the bounded impact is disclosure of memory visible to the Bluetooth process.
