CVE-2014-6268 [MEDIUM] CVE-2014-6268 kernel: xen: Mishandling of uninitialised FIFO-based event channel control blocks (xsa107)
CVE-2014-6268 kernel: xen: Mishandling of uninitialised FIFO-based event channel control blocks (xsa107)
When using the FIFO-based event channels, there are no checks for the
existence of a control block when binding an event or moving it to a
different VCPU. As a result, a buggy or malicious guest can crash the
host.
