In the handler for the ioctl command VIDIOC_MSM_ISP_DUAL_HW_LPM_MODE in Android for MSM, Firefox OS for MSM, and QRD Android before 2017-05-23, a heap overread vulnerability exists.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
