# Memory corruption in Graphics Linux while assigning shared virtual memory region during IOCTL call

Multiple Qualcomm chipsets have an integer overflow in the Graphics Linux driver when assigning a shared virtual memory region during an IOCTL call, causing memory corruption. Listed by CISA as actively exploited, so an attacker with a way to reach the driver can likely corrupt kernel memory and gain control of the device.

_Summary, check and fix written by a model from the sources; labelled as such._
