Detailsinfo

A vulnerability, which was classified as critical, was found in Google Android on Qualcomm (Smartphone Operating System) (unknown version). Affected is the function boot_clobber_check_local_address_range. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile and Snapdragon Wear IPQ4019, MDM9206, MDM9607, MDM9615, MDM9625, MDM9635M, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD 600, SD 615/16/SD 415, SD 808, and SD 810, if start_addr + size is too large in boot_clobber_check_local_address_range(), an integer overflow occurs, resulting in clobber protection check being bypassed and SBL memory corruption.

The bug was discovered 04/05/2018. The weakness was released 04/18/2018 (Website). The advisory is shared for download at source.android.com.
