The issue occurs while handling a \"PVRDMA_REG_DSRHIGH\" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability."
