Detailsinfo

A vulnerability has been found in Google Android (Smartphone Operating System) (affected version unknown) and classified as critical. Affected by this vulnerability is the function wma_unified_link_radio_stats_event_handler of the component Qualcomm. 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 summary by CVE is:

In all Qualcomm products with Android releases from CAF using the Linux kernel, in wma_unified_link_radio_stats_event_handler(), the number of radio channels coming from firmware is not properly validated, potentially leading to an integer overflow vulnerability followed by a buffer overflow.

The bug was discovered 02/05/2018. The weakness was disclosed 02/23/2018 (Website). The advisory is shared at source.android.com. This vulnerability is known as CVE-2017-15862 since 10/24/2017. The exploitation appears to be easy. An attack has to be approached locally. The exploitation doesn't need any form of authentication. Technical details are known, but no exploit is available.
