+Subject: PATCH fb: properly wrap/unwrap CloseScreen
+
+fbCloseScreen assumes that it overrides miCloseScreen (which just
+calls FreePixmap(screen->devPrivates)) and emulates that instead of
+wrapping it.
+
+This is a wrong assumption, we may have ShmCloseScreen in the mix too,
+resulting in leaks (see below). Fix this by properly setting up the
+CloseScreen wrapper.
+
+This means we no longer need the manual DestroyPixmap call in
+vfbCloseScreen, reverting d348ab06aae21c153ecbc3511aeafc8ab66d8303

+Subject: PATCH dix: always initialize pScreen->CloseScreen
+
+CloseScreen is wrapped by the various modules, many of which do not
+check if they're the last ones unwrapping. This is fine if the order of
+those modules never changes but when it does we might get a NULL-pointer
+dereference by some naive code doing a
+
+   pScreen->CloseScreen = priv->CloseScreen;
+   free(priv);
+   return (*pScreen->CloseScreen)(pScreen);
+
+To avoid this set it to a default function that just returns TRUE that's
+guaranteed to be the last one.

+Subject: PATCH xkb: Fix buffer overflow in _XkbSetCompatMap()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+origin: https://gitlab.freedesktop.org/xorg/xserver/-/commit/85b776571487f52e756f68a069c768757369bfe3
+
+The _XkbSetCompatMap() function attempts to resize the `sym_interpret`
+buffer.
+
+However, It didn't update its size properly. It updated `num_si` only,
+without updating `size_si`.
+
+This may lead to local privilege escalation if the server is run as root
+or remote code execution (e.g. x11 over ssh).
