Score breakdown

In binder_transaction of binder.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-136210786References: Upstream kernel

From the Ubuntu Security Team

It was discovered that the binder IPC implementation in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
