Detailsinfo

A vulnerability classified as critical has been found in Qualcomm Snapdragon Automobile and Snapdragon Mobile (Chip Software). Affected is an unknown code block of the component HLOS Client Handler. The manipulation with an unknown input leads to a race condition vulnerability (Kernel Memory). CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In Snapdragon (Automobile ,Mobile) in version MSM8996AU, SD 425, SD 427, SD 430, SD 435, SD 450, SD 625, SD 650/52, SD 820, SD 820A, SD 835, SDA660, SDM429, SDM439, SDM630, SDM632, SDM636, SDM660, Snapdragon_High_Med_2016, a crafted HLOS client can modify the structure in memory passed to a QSEE application between the time of check and the time of use, resulting in arbitrary writes to TZ kernel memory regions.

The bug was discovered 08/01/2018. The weakness was published 09/20/2018 (Website). The advisory is available at source.android.com. This vulnerability is traded as CVE-2017-18302 since 06/15/2018.
