MIT Researchers Expose TONTOU Attack Bypassing Spectre Defenses on Intel, AMD CPUs
MIT researchers have uncovered a clever new attack, dubbed TONTOU, that can bypass Spectre defenses on Intel and AMD CPUs, revealing a practical exploit on AMD Zen 2. This innovative technique, presented at DEF CON 34, challenges current security assumptions and opens up new avenues for exploration.
Interrupt Injection Attack Bypasses Spectre v2 Defenses on Intel, AMD CPUs
Researchers have uncovered a shocking vulnerability that allows an unprivileged local program to bypass Spectre v2 defenses on Intel and AMD CPUs, leaking kernel memory with alarming speed and accuracy. On an AMD Zen 2 system, this exploit can siphon off sensitive data at a rate of 5.47 bytes per second with near 92% accuracy, making it possible to crack even highly secured files like /etc/shadow.
Linux Flaw Enables VM Escape on Intel, AMD Devices
A newly disclosed 16-year-old Linux kernel vulnerability, dubbed Januscape, allows hackers to easily escape virtual machines and compromise their host systems - all with just a few clicks from within the guest system. This shocking security flaw, tracked as CVE-2026-53359, has been lurking in the kernel for nearly two decades.
Linux KVM Flaw Lets Guest VMs Escape to Host on Intel, AMD Systems
A newly discovered 16-year-old flaw in Linux's KVM, nicknamed "Januscape," allows guest virtual machines to break free and interact with their host systems on Intel and AMD machines, potentially leading to full host code execution. This vulnerability, tracked as CVE-2026-53359, can cause a host to panic and be exploited for malicious purposes.
