Summary
fuse-uring: Avoid use-after-free in fuse_uring_async_stop_queues
Details

In the Linux kernel, the following vulnerability has been resolved:

fuse-uring: Avoid use-after-free in fuseuringasyncstopqueues

fuseuringasyncstopqueues() might run when the last reference on ring->queue_refs was already dropped.

In order to avoid an early destruction a reference on struct fuseconn is now taken before starting fuseuringasyncstop_queues() and that reference is only released when that delayed work queue terminates.
