UBUNTU-CVE-2020-29571

An issue was discovered in Xen through 4.14.x. A bounds check common to most operation time functions specific to FIFO event channels depends on the CPU observing consistent state. While the producer side uses appropriately ordered writes, the consumer side isn't protected against re-ordered read...

UBUNTU-CVE-2020-29566

An issue was discovered in Xen through 4.14.x. When they require assistance from the device model, x86 HVM guests must be temporarily de-scheduled. The device model will signal Xen when it has completed its operation, via an event channel, so that the relevant vCPU is rescheduled. If the device...

Xen Platypus information leak via power sidechannel (XSA-351)

An information disclosure vulnerability exists in power/energy monitoring interfaces, which can be used to create covert channels and infer the operations and data used by other contexts within the system. C Tenable Network Security, Inc. include'compat.inc'; if description scriptid142889;...

CVE-2020-28368

A flaw was found in Xen where access to power/energy monitoring interfaces was not properly restricted to privileged software. This flaw allows an unprivileged guest administrator to create covert channels and infer the operations or data used by other contexts within the system, such as AES keys...

Information leak via power sidechannel

ISSUE DESCRIPTION Researchers have demonstrated using software power/energy monitoring interfaces to create covert channels, and infer the operations/data used by other contexts within the system. Access to these interfaces should be restricted to privileged software, but it was found that Xen...

UBUNTU-CVE-2020-27675

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/eventsbase.c allows event-channel removal during the event-handling loop a race condition. This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash vi...
