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.
