Impact

goodix_tool.c in the Goodix gt915 touchscreen driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not properly synchronize updates to a global variable, which allows local users to bypass intended access restrictions or cause a denial of service (memory corruption) via crafted arguments to the procfs write handler.
