CVE-2019-11085

Published: 17 May 2019

Insufficient input validation in Kernel Mode Driver in Intel(R) i915 Graphics for Linux before version 5.0 may allow an authenticated user to potentially enable escalation of privilege via local access.

From the Ubuntu Security Team

Adam Zabrocki discovered that the Intel i915 kernel mode graphics driver in the Linux kernel did not properly restrict mmap() ranges in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
