CVE-2018-9482

Local information disclosure via interrupt-report length wraparound

Published Nov 20, 2024 · Updated Nov 20, 2024

Out-of-bounds read in Android 8.0, 8.1, and 9 allows local users to disclose Bluetooth service memory without user interaction. In intr_data_copy_cb in btif_hd.cc, a wrapped interrupt-report length reaches memcpy, which reads beyond the source data. Exploitation requires local access but no additional execution privileges or user interaction, and the documented impact is disclosure only.
