drivers/gpu/msm/kgsl.c in the Qualcomm Innovation Center (QuIC) Graphics KGSL kernel-mode driver for Android 2.3 through 4.2 allows attackers to cause a denial of service (NULL pointer dereference) via an application that uses crafted arguments in a local kgsl_ioctl call.

The Zygote process in Android 4.0.3 and earlier accepts fork requests from processes with arbitrary UIDs, which allows remote attackers to cause a denial of service (reboot loop) via a crafted application.
