+Subject: [PATCH] Cursor: Refuse to free the root cursor
+
+If a cursor reference count drops to 0, the cursor is freed.
+
+The root cursor however is referenced with a specific global variable,
+and when the root cursor is freed, the global variable may still point
+to freed memory.
+
+Make sure to prevent the rootCursor from being explicitly freed by a
+client.
+
+CVE-2025-26594, ZDI-CAN-25544

+Subject: [PATCH] dix: keep a ref to the rootCursor
+
+CreateCursor returns a cursor with refcount 1 - that refcount is used by
+the resource system, any caller needs to call RefCursor to get their own
+reference. That happens correctly for normal cursors but for our
+rootCursor we keep a variable to the cursor despite not having a ref for
+ourselves.
+
+Fix this by reffing/unreffing the rootCursor to ensure our pointer is
+valid.
