Description
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.
