drivers/gpu/msm/kgsl.c in the MSM graphics driver (aka GPU driver) for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, mishandles the KGSL_MEMFLAGS_GPUREADONLY flag, which allows attackers to gain privileges by leveraging accidental read-write mappings, aka Qualcomm internal bug CR988993.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
