GPUs are found in millions of devices, allowing for stunning imagery to be generated on phones, tablets, and televisions. However, if we take a deeper look at how GPUs are programmed, the overall picture becomes much more bleak. GPUs directly accessing CPU memory, sensitive images not being cleared from graphics memory, and thin graphic APIs wrapping vendor specific implementations paint a darker picture. Recently discovered privilege escalation and DoS vulnerabilities uncovered by NCC Group will be discussed. These vulnerabilities affect many popular devices.
