Meltdown patch causes problems for Windows 7

Windows operating systems are affected by the patch released to fix the Meltdown software bug.

Threat: Windows 7 x64 and Windows 2008 R2 x64 systems that have installed the patch for Meltdown, which was released in January, are vulnerable to a kernel memory flaw.

Damage risk: The vulnerability would allow an attacker to read from and write to the entire contents of system memory. Attackers could run code on the affected platform as unprivileged users, which would allow them unfettered access to the system memory.

Exploited flaw: The Meltdown patch sets the permission bit for memory accessible from unprivileged user space, meaning the system memory isn’t protected.

Fixes/Workarounds: Microsoft released security updates to fix the problem.
