In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile, Snapdragon Mobile, Snapdragon Wear, and Small Cell SoC FSM9055, IPQ4019, MDM9206, MDM9607, MDM9625, MDM9635M, MDM9640, MDM9645, MDM9650, MDM9655, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 425, SD 430, SD 450, SD 600, SD 615/16/SD 415, SD 617, SD 625, SD 650/52, SD 800, SD 808, SD 810, SD 820, SD 820A, SD 835, SD 845, SD 850, and SDX20, when an RSA encryption operation is called, the ce_util_to_unsigned_bin is invoked to convert the input buffer to unsigned binary. The ce_util_to_unsigned_bin function, instead of operating on the size of the unsigned character buffer that is passed, operates on the address - i.e. operates on "c" instead of "*c". Decrementing the address to check if it is less than zero means that the operation will always pass, since a pointer will never be less than zero, and may result in a buffer overflow.

Security readout for executives and security teams

This is a Qualcomm Snapdragon Android platform flaw fixed by Android security patch level 2018-04-05. A crypto-related coding error may cause a buffer overflow during RSA encryption handling. Business risk is concentrated in older or unsupported Android, automotive, wearable, small-cell, or embedded devices using the listed Snapdragon SoCs. Likely exposure is legacy Android or embedded devices on the listed Qualcomm Snapdragon Automobile, Mobile, Wear, and Small Cell SoCs with patch levels before 2018-04-05. Current supported devices with later OEM security updates are less likely exposed, but firmware lineage should be verified. Treat as an asset-management and legacy-platform risk. It is not supported here as an emergency active-exploitation issue, but older Qualcomm-based Android and embedded fleets should be identified and patched or retired because no severity score is available. Mitigation focus: Confirm affected devices have Android security patch level 2018-04-05 or later.; Apply OEM or Qualcomm-provided firmware updates where available.; Prioritize replacement or isolation for unsupported affected platforms..
