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