+Fix multiplying a list by an integer (``list *= int``): detect the integer
+overflow when the new allocated length is close to the maximum size. Issue

+.. section: Security
+
+On Linux the :mod:`multiprocessing` module returns to using filesystem
+backed unix domain sockets for communication with the *forkserver* process
+instead of the Linux abstract socket namespace.  Only code that chooses to
+use the :ref:`"forkserver" start method <multiprocessing-start-methods>` is
+affected.
+
+Abstract sockets have no permissions and could allow any user on the system
+in the same `network namespace
+<https://man7.org/linux/man-pages/man7/network_namespaces.7.html>`_ (often
+the whole system) to inject code into the multiprocessing *forkserver*
+process. This was a potential privilege escalation. Filesystem based socket
+permissions restrict this to the *forkserver* process user as was the
+default in Python 3.8 and earlier.
+
+This prevents Linux `CVE-2022-42919
+<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-42919>`_.

+.. nonce: Rf-C6u
+.. section: macOS
+
+The macOS 13 SDK includes support for the ``mkfifoat`` and ``mknodat``
+system calls. Using the ``dir_fd`` option with either :func:`os.mkfifo` or
+:func:`os.mknod` could result in a segfault if cpython is built with the
+macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding
+runtime support for detection of these system calls ("weaklinking") as is
+done for other newer syscalls on macOS.

-Using the ``dir_fd`` option with either :func:`os.mkfifo` or :func:`os.mknod` could result in a
-segfault if cpython is built with the macOS 13 SDK but run on an earlier
-version of macOS. Prevent this by adding runtime support for detection of
-these system calls ("weaklinking") as is done for other newer syscalls on
-macOS.
