The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.
Samsung devices with Android KK(4.4) or L(5.0/5.1) allow local users to cause a denial of service (IAndroidShm service crash) via crafted data in a service call.
3) Integer overflow (CVE-ID: CVE-2016-9277)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
Integer overflow in SystemUI in KK(4.4) and L(5.0/5.1) on Samsung Note devices allows attackers to cause a denial of service (UI restart) via vectors involving APIs and an activity that computes an out-of-bounds array index, aka SVE-2016-6906.
