  "description": "In the Linux kernel, the following vulnerability has been resolved:  af_unix: Return immediately when manage_oob() returns NULL for 0-length buffer.  Fahad Alharbi reported that recv(0, MSG_PEEK) triggers busy-wait in unix_stream_read_generic() if recv() is blocking and the last skb in the queue is MSG_OOB skb.  In such a situation, TCP returns 0 immediately regardless of blocking or non-blocking.  Let\u0027s follow the behaviour.",
