An elevation of privilege vulnerability in libnl could enable a local malicious application to execute arbitrary code within the context of the Wi-Fi service. This issue is rated as Moderate because it first requires compromising a privileged process and is mitigated by current platform configurations. Product: Android. Versions: 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1. Android ID: A-32342065. NOTE: this issue also exists in the upstream libnl before 3.3.0 library.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
