Description

In the Linux kernel, the following vulnerability has been resolved: io_uring/af_unix: disable sending io_uring over sockets File reference cycles have caused lots of problems for io_uring in the past, and it still doesn&#39;t work exactly right and races with unix_stream_read_generic(). The safest fix would be to completely disallow sending io_uring files via sockets via SCM_RIGHT, so there are no possible cycles invloving registered files and thus rendering SCM accounting on the io_uring side unnecessary.
