-Subject: [PATCH] rtl8139: fix possible out of bound access
-
-In rtl8139_do_receive(), we try to assign size_ to size which converts
-from size_t to integer. This will cause troubles when size_ is greater
-INT_MAX, this will lead a negative value in size and it can then pass
-the check of size < MIN_BUF_SIZE which may lead out of bound access of
-for both buf and buf1.
-
-Fixing by converting the type of size to size_t.
