CVE-2017-1000252 [MEDIUM] KVM: VMX: Do not BUG() on out-of-bounds guest IRQ
KVM: VMX: Do not BUG() on out-of-bounds guest IRQ
The value of the guest_irq argument to vmx_update_pi_irte() is
ultimately coming from a KVM_IRQFD API call. Do not BUG() in
vmx_update_pi_irte() if the value is out-of bounds. (Especially,
since KVM as a whole seems to hang after that.)
Instead, print a message only once if we find that we don't have a
route for a certain IRQ (which can be out-of-bounds or within the
array).
This fixes CVE-2017-1000252.

CVE-2017-1000252 kernel: kvm: Reachable BUG() on out-of-bounds guest IRQ
A reachable assertion failure flaw was found in the Linux kernel built with the
KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature
(CONFIG_VFIO) enabled. This could occur if a malicious guest device sent a
virtual interrupt(guest IRQ) with larger(>1024) index value.
A guest user/process could use this flaw to crash the KVM hypervisor resulting in Dos.
Note: It affects x86 arch platforms.
