Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Linux kernel's Tegra DRM gr2d and gr3d drivers (3.10 onward) can accept userspace jobs before the register map is initialized. The source gives few details on who can exploit this or what the impact is. Upgrade to 6.1.191, 6.6.145, 6.12.97, 6.18.40, or a later release in those series.
