+Subject: [PATCH] [3.10] gh-97514: Don't use Linux abstract sockets for
+ multiprocessing (GH-98501) (GH-98503)
+
+Linux abstract sockets are insecure as they lack any form of filesystem
+permissions so their use allows anyone on the system to inject code into
+the process.
+
+This removes the default preference for abstract sockets in
+multiprocessing introduced in Python 3.9+ via
+https://github.com/python/cpython/pull/18866 while fixing
+https://github.com/python/cpython/issues/84031.
+
+Explicit use of an abstract socket by a user now generates a
+RuntimeWarning.  If we choose to keep this warning, it should be
+backported to the 3.7 and 3.8 branches.
+(cherry picked from commit 49f61068f49747164988ffc5a442d2a63874fc17)

++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
