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