CVE-2019-16508
Last modified
CVE-2019-16508 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The Imagination Technologies driver for Chrome OS before R74-11895.B, R75 before R75-12105.B, and R76 before R76-12208.0.0 allows attackers to trigger an Integer Overflow and gain privileges via a malicious application. This occurs because of intentional access for the GPU process to /dev/dri/card1 and the PowerVR ioctl handler, as demonstrated by PVRSRVBridgeSyncPrimOpCreate.. EPSS estimates a 0.50% chance of exploitation in the next 30 days.
