    New CPU Cache Timing Attack Bypasses Windows 11 Kernel Address Space Randomization

    In the constant cat-and-mouse game between operating system security engineers and determined attackers, Kernel Address Space Layout Randomization (KASLR) remains one of the most crucial defenses in modern computing. Trusted by Windows 11 and earlier versions, KASLR aims to keep attackers...
