Red Hat statement

Red Hat Product Security is aware of this issue. Updates will be released as they become available. For additional information, please refer to the Red Hat Knowledgebase article: https://access.redhat.com/solutions/i915-graphics

Red Hat mitigation

Preventing loading of the i915 kernel module will prevent attackers from using this exploit against the system however the power management functionality of the card will be disabled and the system may draw additional power. See this KCS article( https://access.redhat.com/solutions/41278 ) for instructions on how to disable a kernel module. Graphical displays may also be at low resolution or not work correctly. This mitigation may not be suitable if running graphical tools locally is required.
