Detailsinfo

A vulnerability, which was classified as very critical, has been found in Linux Kernel 3.x (Operating System). This issue affects an unknown functionality of the file mdss_compat_utils.c of the component MDSS Driver. The manipulation of the argument size with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple integer overflows in the MDSS driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allow attackers to cause a denial of service or possibly have unspecified other impact via a large size value, related to mdss_compat_utils.c, mdss_fb.c, and mdss_rotator.c.

The weakness was released 08/30/2016 with Qihoo 360 (Website). The advisory is shared at securityfocus.com. The identification of this vulnerability is CVE-2016-5344 since 06/09/2016. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation.
