Reading privileged memory with a side-channel (Meltdown & Spectre)

We have discovered that CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to at worst arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Variants of this issue are known to affect many mode...

KB4056890: Windows 10 Version 1607 and Windows Server 2016 January 2018 Security Update (Meltdown)(Spectre)

(RHSA-2018:0011) Important: kernel security update

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three...

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...
