Experts Weigh In On Spectre Patch Challenges

The race to patch against the Meltdown and Spectre processor vulnerabilities disclosed last week is on. As of today, there are no known exploits in the wild impacting vulnerable Intel, AMD and ARM devices. Currently, vendors are focused on three main mitigation efforts. Patches that address the...

Important kernel security update: Fixes for Meltdown and Spectre exploits; new kernel 2.6.32-042stab127.2, Virtuozzo 6.0 Update 12 Hotfix 20 (6.0.12-3690)

This update provides a new Virtuozzo 6.0 kernel 2.6.32-042stab127.2 that is a rebase to the Red Hat Enterprise Linux 6.9 kernel 2.6.32-696.18.7.el6. The rebase fixes an industry-wide issue that was found in the way many modern microprocessor designs have implemented speculative execution of...

Information leak via side effects of speculative execution

ISSUE DESCRIPTION Processors give the illusion of a sequence of instructions executed one-by-one. However, in order to most efficiently use cpu resources, modern superscalar processors actually begin executing many instructions in parallel. In cases where instructions depend on the result of...
