USN-2843-2 linux-lts-wily vulnerabilities
Jan Beulich discovered that the KVM svm hypervisor implementation in the Linux kernel did not properly catch Debug exceptions on AMD processors. An attacker in a guest virtual machine could use this to cause a denial of service system crash in the host OS. CVE-2015-8104 郭永刚 discovered that the pp...

virt: guest to host DoS by triggering an infinite loop in microcode via #DB exception
It was found that the x86 ISA Instruction Set Architecture is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way sequential delivering of benign exceptions such as DB debug exception is handled. A privileged user...
