In the Linux kernel, the following vulnerability has been resolved:
btrfs: don't stash io_uring encoded data across -EAGAIN
Returning -EAGAIN while leaving btrfs_uring_encoded_data in the cmd PDU
leaks if the request is cancelled or the ring exits before reissue.
io_uring does not free driver PDU allocations on cleanup.
Write: io_queue_sqe() always issues with IO_URING_F_NONBLOCK first, so
return -EAGAIN before allocating and free data on every exit.
Read: free on nowait -EAGAIN too; only -EIOCBQUEUED keeps the allocation
for btrfs_uring_read_finished().
