A vulnerability classified as critical was found in Google Android (Smartphone Operating System) (the affected version unknown). This vulnerability affects an unknown part of the component Qualcomm Crypto Engine Driver. The manipulation with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. 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 can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was presented 10/05/2016 by Seven Shen with Trend Micro as Android Security Bulletin - October 2016 as confirmed security bulletin (Website). The advisory is shared for download at source.android.com. This vulnerability was named CVE-2016-3901 since 03/30/2016. The attack needs to be approached locally. A single authentication is necessary for exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 09/22/2022). It is expected to see the exploit prices for this product increasing in the near future.

Upgrading eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
