Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns a potential vm use-after-free in the Linux kernel, specifically in the drm/i915 component.

To mitigate this, an extra reference is taken before putting the vm in the table.
