What it is

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

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

fuse_uring_async_stop_queues() might run when the last reference

on ring->queue_refs was already dropped.

In order to avoid an early destruction a reference on struct fuse_conn

is now taken before starting fuse_uring_async_stop_queues() and that

reference is only released when that delayed work queue terminates.
