      "title": "drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()\n\nTwo error handling issues exist in xe_exec_queue_create_ioctl():\n\n1. When xe_hw_engine_group_add_exec_queue() fails, the error path jumps\n   to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in\n   preempt fence mode, xe_vm_add_compute_exec_queue() has already added\n   the queue to the VM's compute exec queue list. Skipping the kill\n   leaves the queue on that list, leading to a dangling pointer after\n   the queue is freed.\n\n2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has\n   succeeded, the error path does not call\n   xe_hw_engine_group_del_exec_queue() to remove the queue from the hw\n   engine group list. The queue is then freed while still linked into\n   the hw engine group, causing a use-after-free.\n\nFix both by:\n- Changing the xe_hw_engine_group_add_exec_queue() failure path to jump\n  to kill_exec_queue so that xe_exec_queue_kill() properly removes the\n  queue from the VM's compute list.\n- Adding a del_hw_engine_group label before kill_exec_queue for the\n  xa_alloc() failure path, which removes the queue from the hw engine\n  group before proceeding with the rest of the cleanup.\n\n(cherry picked from commit 37c831f401746a45d510b312b0ed7a77b1e06ec8)",
