Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the implementation of VMWare's paravirtual RDMA device via the pvrdma_ring_next_elem_read() function. Exploiting this vulnerability allows a crafted guest driver to allocate and initialize a massive number of page tables to be used as a ring of descriptors for CQ and async events.
