In the Linux kernel, the following vulnerability has been resolved:
io_uring/rw: free potentially allocated iovec on cache put failure
If a read/write request goes through io_req_rw_cleanup() and has an
allocated iovec attached and fails to put to the rw_cache, then it may
end up with an unaccounted iovec pointer. Have io_rw_recycle() return
whether it recycled the request or not, and use that to gauge whether to
free a potential iovec or not.
