What it is

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

fuse-uring: Avoid queue->stopped races and set/read that value under lock

There are several readers of queue->stopped that check the value

under lock, but fuse_uring_commit_fetch() did not and actually

the value was not set under the lock in fuse_uring_abort_end_requests()

either. Especially in fuse_uring_commit_fetch it is important

to check under a lock, because due to races 'struct fuse_req'

might be freed with fuse_request_end, but another thread/cpu

might already do teardown work.
