  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/amdgpu: fix sync handling in amdgpu_dma_buf_move_notify  Invalidating a dmabuf will impact other users of the shared BO. In the scenario where process A moves the BO, it needs to inform process B about the move and process B will need to update its page table.  The commit fixes a synchronisation bug caused by the use of the ticket: it made amdgpu_vm_handle_moved behave as if updating the page table immediately was correct but in this case it's not.  An example is the following scenario, with 2 GPUs and glxgears running on GPU0 and Xorg running on GPU1, on a system where P2P PCI isn't supported:  glxgears:   export linear buffer from GPU0 and import using GPU1   submit frame rendering to GPU0   submit tiled-\u003elinear blit Xorg:   copy of linear buffer  The sequence of jobs would be:   drm_sched_job_run                       # GPU0, frame rendering   drm_sched_job_queue                     # GPU0, blit   drm_sched_job_done                      # GPU0, frame rendering   drm_sched_job_run                       # GPU0, blit   move linear buffer for GPU1 access      #   amdgpu_dma_buf_move_notify -\u003e update pt # GPU0  It this point the blit job on GPU0 is still running and would likely produce a page fault.",
