kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free

A use-after-free vulnerability was found in the Linux kernel Intel i915 graphics driver's GuC virtual engine request handling. A local user with access to GPU rendering can create requests on GuC virtual engines and trap references via syncfile or dmabuf, causing fence release operations to acces...

The vulnerabilities of components such as blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls in the Xen hypervisor allow a malicious actor to cause service failures.

The vulnerabilities of the components blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls in the Xen hypervisor are caused by synchronization errors when using a shared resource. Exploiting these vulnerabilities can allow attackers to cause service failures...
