The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in sdeevtlogfilterwrite in drivers/gpu/drm/msm/sdedbg.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

The ft5x46 touchscreen driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the size argument in tpdbgwrite in drivers/input/touchscreen/ft5x46/ft5x46ts.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

The msm gpu driver for custom Linux kernels on the Xiaomi perseus-p-oss MIX 3 device through 2018-11-26 has an integer overflow and OOPS because of missing checks of the count argument in sdedebugfsconncmdtxwrite in drivers/gpu/drm/msm/sde/sdeconnector.c. This is exploitable for a device crash via a syscall by a crafted application on a rooted device.

drivers/leds/leds-aw2023.c in the led driver for custom Linux kernels on the Xiaomi Redmi 6pro daisy-o-oss phone has several integer overflows because of a left-shifting operation when the right-hand operand can be equal to or greater than the integer length. This can be exploited by a crafted application for denial of service.
