CVE-2023-1544: Qemu: pvrdma: out-of-bounds read in pvrdma_ring_next_elem_read()
First published: Tue Mar 21 2023(Updated: )
A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU.
