CVE-2017-17766: Android for MSM may overflow memory due to peer count
CVE-2017-17766 · published 8 years ago
Summary
The Android versions for MSM devices and QRD Android released before October 2017 can miscalculate how much memory to reserve when they receive data about nearby peers. This miscalculation could let an attacker cause the system to write past the intended memory area, potentially leading to crashes or unauthorized code execution. Updating the device to the latest Android release or applying the vendor's security patch resolves the issue.
