Improper Access Control in Multimedia in Snapdragon Mobile and Snapdragon Wear, Non-standard applications without permission may acquire permission of Qualcomm-specific proprietary intents.
Due to Improper Access Control of NAND-based EFS in Snapdragon Automobile, Snapdragon Mobile and Snapdragon Wear, From fastboot on a NAND-based device, the EFS partition can be erased. Apps processor then has non-secure world full read/write access to the partition until the modem boots and configures the EFS partition addresses in its MPU partition.
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile MDM9635M, MDM9645, MDM9650, MDM9655, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 427, SD 430, SD 435, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 810, SDM630, SDM636, SDM660, and Snapdragon_High_Med_2016, stopping of the DTR prematurely causes micro kernel to be stuck. This can be triggered with a timing change injectable in RACH procedure.
