The sockets subsystem in Android 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-07-01 allows attackers to gain privileges via a crafted application that uses (1) the AF_MSM_IPC socket class or (2) another socket class that is unrecognized by SELinux, aka internal bug 28612709.
Weaknesses in this category are related to the management of permissions, privileges, and other security features that are used to perform access control.
