CVE-2015-8104 – virt: guest to host DoS by triggering an infinite loop in microcode via #DB exception

https://notcve.org/view.php?id=CVE-2015-8104

The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c. El subsistema KVM en el kernel Linux hasta la versión 4.2.6, y Xen 4.3.x hasta la versión 4.6.x permite a usuarios del SO invitados causar una denegación de servicio (panic en el host del SO o cuelgue) desencadenando muchas excepciones #DB (también conocidas como Debug), relacionadas con svm.c. 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 inside a guest could use this flaw to create denial of service conditions on the host kernel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cbdb967af3d54993f5814f1cee0ed311a055377d http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172187.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172300.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172435.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http:/&# • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

CVE-2015-5307 – virt: guest to host DoS by triggering an infinite loop in microcode via #AC exception

https://notcve.org/view.php?id=CVE-2015-5307

The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c.
