Summary
In the Linux kernel, the following vulnerability has been resolved: drm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered The host1x_client_register() function is called just prior to register map initialization loop, making the device available to userspace. This may result in userspace attempting to submits a job before the register map is initialized. Address this by moving register initialization before host1x client registration.
