Описание

A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability.

The versions of qemu-kvm as shipped with Red Hat Enterprise Linux and RHEL Advanced Virtualization are not affected by this flaw, as they are not built with PVRDMA support.
