Here's what you need to know about each update to the current version of Windows 10 as it's released from Microsoft. Now updated for KB5035941 Preview, released on March 26, 2024.

Sent in this morning via the 'x86/urgent' pull request ahead of the Linux 6.8-rc6 kernel later today is a set of patches from Intel to ensure clearing of CPU buffers using the VERW instruction happens at the latest possible point in the return-to-userspace code path

An Intel engineer on Friday posted a set of Linux kernel patches that are working to refine the Microarchitectural Data Sampling (MDS) mitigation handling for the Linux kernel to better protect some kernel data and also some very subtle performance benefits.

A new power side-channel attack named Collide+Power can allow an attacker to obtain sensitive information and it works against any modern CPU.

Following a security disclosure by Intel way back in June of last year about vulnerabilities affecting its processors, Microsoft has issued a series of out-of-band fixes for the flaws.

Getty Images In January 2018, the entire computer industry was put on alert by two new processor vulnerabilities dubbed Meltdown and Spectre that defeated the fundamental OS security boundaries separating kernel and user space memory. The flaws stemmed from a performance feature of modern CPUs known as speculative execution and mitigating them required one of the biggest patch coordination efforts in history, involving CPU makers, device manufacturers and operating system vendors...
