CVE-2015-9157 Information

Description

In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear IPQ4019 MDM9206 MDM9607 MDM9625 MDM9635M MSM8909W SD 210/SD 212/SD 205 SD 400 SD 410/12 SD 600 SD 615/16/SD 415 SD 617 SD 650/52 SD 800 SD 808 and SD 810 in widevine_dash_cmd_handler() rsp buffers are passed off to widevine commands. These rsp buffers have values in them such as buffer lengths that need to be validated to ensure that no buffer overflow/over-reads happen. However rsp buffers are not always in locked memory meaning a time-of-check time-of-use issue can occur where we check that the value is valid but then a race condition occurs where this memory is swapped out with a different possibly out of range value.
