The reports points out the design flaw in Intel processors allows normal programs to access crucial kernel memory.

Again, the CPU exploits in play here are extremely technical, but in a nutshell, the exploit allows access to your operating system's sacrosanct kernel memory because of how the processors handle «speculative execution,» which modern chips perform to increase performance.

Some are speculating that Microsoft will deliver this in an upcoming Patch Tuesday, as the company started separating the NT kernel memory with Windows 10 beta builds in November.

Meltdown primarily affects Intel processors, and works by breaking through the barrier that prevents applications from accessing arbitrary locations in kernel memory.

The flaws allow an attacker to use malware in user mode to reveal the contents of kernel memory, which should not normally be allowed and could result in the leakage of sensitive information, such as passwords.

As the name suggests, KAISER seeks to defend the kernel memory from a so - called side - channel attack that exploits a design feature of modern processors that increases their speed.

It can be helpful for identifying the error, but offers less detailed debugging information than a kernel memory dump.

Sure — you will get a less accurate memory dump (with some zeros here and there), but won't this still mean you can get a somewhat estimated guess of the kernel memory contents?

Crashes are usually caused by code running in kernel - mode, so the complete information including each program's memory is rarely useful — a kernel memory dump will usually be sufficient even for a developer.

Microsoft says that, when the page file is set to a system - managed size and the computer is configured for automatic memory dumps, «Windows sets the size of the paging file large enough to ensure that a kernel memory dump can be captured most of the time.»
