The adreno_perfcounter_query_group function in drivers/gpu/msm/adreno_perfcounter.c in the Adreno GPU driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, uses an incorrect integer data type, which allows attackers to cause a denial of service (integer overflow, heap-based buffer overflow, and incorrect memory allocation) or possibly have unspecified other impact via a crafted IOCTL_KGSL_PERFCOUNTER_QUERY ioctl call. La función adreno_perfcounter_query_group en drivers/gpu/msm/adreno_perfcounter.c en el controlador Adreno GPU para el kernel de Linux 3.x, según se utiliza en Qualcomm Innovation Center (QuIC) Android contributions for MSM devices y otros productos, utiliza un tipo de datos entero incorrecto, lo que permite a atacantes provocar una denegación de servicio (desbordamiento de entero, desbordamiento de buffer basado en memoria dinámica y asignación de memoria incorrecta) o posiblemente tener otro impacto no especificado a través de una llamada ioctl IOCTL_KGSL_PERFCOUNTER_QUERY. • http://source.android.com/security/bulletin/2016-06-01.html http://www.securitytracker.com/id/1035766 https://codeaurora.org/cgit/quic/la/kernel/msm-3.18/commit/?id=27c95b64b2e4b5ff1288cbaa6e353dd803d71576 https://www.codeaurora.org/buffer-overflow-adreno-gpu-msm-driver-cve-2016-2062 • CWE-190: Integer Overflow or Wraparound •
