Details

In the Linux kernel, the following vulnerability has been resolved:

KVM: x86/xen: Fix cleanup logic in emulation of Xen schedop poll hypercalls

kvmxenschedoppoll does a kmallocarray() when a VM polls the host for more than one event channel potr (nr_ports > 1).

After the kmallocarray(), the error paths need to go through the "out" label, but the call to kvmreadguestvirt() does not.
