CVE-2019-2170

Vulnerability

The vulnerability resides in the libxaac library component of Android 10 (version 10). The issue is triggered by uninitialized data, which can lead to information disclosure. Affected devices are those running Android 10 with a security patch level before 2019-09-01 [1].

Exploitation

An attacker requires user interaction to trigger the vulnerable code path. No additional execution privileges beyond normal user access are needed. The exact sequence of steps is not detailed in the available references, but the uninitialized data condition is reachable through crafted input processed by the libxaac library.

Impact

Successful exploitation could lead to information disclosure, potentially exposing sensitive data on the device. The attacker does not gain elevated privileges or code execution; the impact is limited to reading uninitialized memory.

Mitigation

Android 10 devices with a security patch level of 2019-09-01 or later are protected against this issue [1]. Users should ensure their devices are updated to the latest security patch level. No workarounds are provided for unpatched devices.
