QID 379509

QID 379509: Khronos Group OpenCL/Vulkan Buffer Overflow Vulnerability (LeftoverLocals)

General-purpose graphics processing unit (GPGPU) platforms from AMD fail to adequately isolate process memory, thereby enabling a local attacker to read memory from other processes. In this situation, a GPU kernel can observe memory values from a different GPU kernel, even when these two kernels are isolated between applications, processes, or users.

QID Detection Logic:

Successful exploitation allows an attacker with access to GPU capabilities using a vulnerable GPU's programmable interface can access memory that is expected to be isolated from other users and processes.

CVSS V3 rated as High - 6.5 severity.

CVSS V2 rated as High - 6.8 severity.
