JSON

A flaw was found in Intel graphics hardware (GPU) where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected displays will remain unusable until a reboot occurs.

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.
