VectorAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
In the Linux kernel, the following vulnerability has been resolved:
nouveau/gem: reserve the bo in the info ioctl around the vma lookup
In the non-uvmm path, there could be a race between the info lookup finding the vma, and the gem close path closing the vma leading to a use-after-free.
Spotted with the help of Opus 4.6.
