Veeam warns of Software Appliance boot failures on AMD EPYC hosts
Veeam warned customers about boot failures affecting Software Appliance virtual machines (VMs) on hosts with AMD EPYC processors. The company’s Software Appliance VMs are pre-configured, Linux-based virtual machines that let admins run the Veeam Backup & Replication backup software suite on Linux devices without manually installing dependencies or configuring the software. To comply with corporate […]
New TONTOU CPU attack bypasses Spectre v2 fixes, leaks Linux password hashes
Successfully exploiting the issue requires overcoming several obstacles, including redirecting kernel control flow, precisely aligning interrupts with the post-neutralization window, and using the interrupt handler to poison the branch predictor entry associated with the target indirect branch. The researchers address these challenges through installing ‘timers’ to trigger hardware interrupts, frequent injection of interrupts, and via […]
New Januscape Linux flaw allows VM escape on Intel, AMD devices
A 16-year-old Linux kernel vulnerability, dubbed Januscape, allows attackers to escape a virtual machine and execute arbitrary code on the host. According to Hyunwoo Kim, the security researcher who discovered it, this guest-to-host escape flaw (tracked as CVE-2026-53359) stems from a use-after-free weakness in the shadow MMU emulation of KVM/x86, the kernel-based virtual machine built for x86 and […]
TEE.Fail attack breaks confidential computing on Intel, AMD, NVIDIA CPUs
Academic researchers developed a side-channel attack called TEE.Fail, which allows extracting secrets from the trusted execution environment in the CPU, the highly secure area of a system, such as Intel’s SGX and TDX, and AMD’s SEV-SNP. The method is a memory-bus interposition attack on DDR5 systems that could be successfully done by computer hobbyists a cost of less than […]
New VMScape attack breaks guest-host isolation on AMD, Intel CPUs
A new Spectre-like attack dubbed VMScape allows a malicious virtual machine (VM) to leak cryptographic keys from an unmodified QEMU hypervisor process running on modern AMD or Intel CPUs. The attack breaks the isolation between VMs and the cloud hypervisor, bypassing existing Spectre mitigations and threatening to leak sensitive data by leveraging speculative execution. The […]
AMD fixes bug that lets hackers load malicious microcode patches
AMD has released mitigation and firmware updates to address a high-severity vulnerability that can be exploited to load malicious CPU microcode on unpatched devices. The security flaw (CVE-2024-56161) is caused by an improper signature verification weakness in AMD’s CPU ROM microcode patch loader. Attackers with local administrator privileges can exploit this weakness, resulting in the loss […]

The Radeon RX 8000 Series GPUs will be based on the innovative RDNA 4 architecture and these GPUs promise better […]
AMD Ryzen 5 vs Intel Core i5: Ultimate Performance Comparison
The mid-range CPU market is known for being the most competitive and AMD and Intel have been battling it out for years with the Ryzen 5 vs Core i5 series. Both offer consumers a wide range of options and each processor family has its own unique strengths and weaknesses, catering to different needs and budgets. […]
Best GPU Settings and Tweaks: Optimizing Performance and Quality
Graphics processing units (GPUs) are essential for gamers, designers, and those working with graphics-intensive tasks. Tweaking your GPU settings can significantly boost your system’s performance, leading to smoother image rendering, improved frame rates, and an overall better visual experience. Each video card comes with a control panel that allows users to customize settings to suit […]
New AMD SinkClose flaw helps install nearly undetectable malware
AMD is warning about a high-severity CPU vulnerability named SinkClose that impacts multiple generations of its EPYC, Ryzen, and Threadripper processors. The vulnerability allows attackers with Kernel-level (Ring 0) privileges to gain Ring -2 privileges and install malware that becomes nearly undetectable. Ring -2 is one of the highest privilege levels on a computer, running […]
