kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...
