Speculative execution is vital to high performance in modern PCs. We discuss how it works and why it's considered a potential security threat.
New speculative execution bug leaks data from Intel chips’ internal buffers Intel-specific vulnerability was found by researchers both inside and outside the company.
We’ve also got to build better mechanisms.” However, that won’t mean getting rid of speculative execution, said Mark Hill, professor of computer science at the University of Wisconsin in Madison. The ...
Academic researchers found two new speculative execution flaws The pair are affecting M2 and M3 processors Apple has acknowledged the flaws, and said it would fix it Apple devices powered with the ...
Such speculative execution is used to avoid slowing down computations by bringing forward certain computational steps before it is clear whether they are actually needed. Speculative calculations take ...
One potential solution in hardware - while avoiding severe loss of performance due to disabled or nerfed speculative execution - would be to have separate and dedicated, 'virtualized' load/store ...
Academic researchers created a new speculative side-channel attack they named iLeakage that works on all recent Apple devices and can extract sensitive information from the Safari web browser.
Meltdown Redux: Intel Flaw Lets Hackers Siphon Secrets from Millions of PCs Two different groups of researchers found another speculative execution attack that can steal all the data a CPU touches.
Google and Microsoft discovered a new CPU flaw related to Meltdown and Spectre. Take action, but don't panic too much about Speculative Store Bypass.
CPU architecture improvements over the years, including speculative execution, now powers “the internet and everything we do,' so it cannot just be turned off.
Spectre and Meltdown are the names given to a trio of variations on a vulnerability that affects nearly every computer chip manufactured in the last 20 years. The flaws are so fundamental and ...
