  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/tegra: gr2d/gr3d: Initialize address register map before HOST1X client is registered\n\nThe host1x_client_register() function is called just prior to register map\ninitialization loop, making the device available to userspace. This may\nresult in userspace attempting to submits a job before the register map is\ninitialized. Address this by moving register initialization before host1x\nclient registration.",
