Description
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86/xen: Fix cleanup logic in emulation of Xen schedop poll hypercalls
kvm_xen_schedop_poll does a kmalloc_array() when a VM polls the host
for more than one event channel potr (nr_ports > 1).
After the kmalloc_array(), the error paths need to go through the
"out" label, but the call to kvm_read_guest_virt() does not.
