In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile SD 835, SD 845, and SD 850, vendor specific opcodes may not have any packet length validation leading to buffer over-reads.
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile, Snapdragon Mobile, and Snapdragon Wear IPQ4019, MDM9206, MDM9607, MDM9650, MSM8909W, SD 210/SD 212/SD 205, SD 410/12, SD 425, SD 430, SD 450, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 808, SD 810, SD 820, SD 820A, SD 835, SD 845, and SD 850, if the buffer length passed to the RIL interface is too large, the buffer size calculation may overflow, resulting in an undersize allocation for the buffer, and subsequently buffer overwrite.
