A 16-year-old Linux kernel vulnerability, dubbed Januscape, allows attackers to escape a virtual machine and execute arbitrary code on the host. [...]
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. [...]
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. [...]
Microsoft has announced that hotpatch updates are now available for business customers using Windows 11 Enterprise 24H2 on x64 (AMD/Intel) systems, starting today. [...]
Microsoft has released the KB5053656 preview cumulative update for Windows 11 24H2 with 38 changes, including real-time translation on AMD and Intel-powered Copilot+ PCs and fixes for authentication and blue-screen issues. [...]
Microsoft is now testing its AI-powered Recall feature on AMD and Intel-powered Copilot+ PCs enrolled in the Windows 11 Insider program. [...]
The latest generations of Intel processors, including Xeon chips, and AMD's older Zen 1, Zen 1+, and Zen 2 microarchitectures on Linux are vulnerable to new speculative execution attacks that bypass existing 'Spectre' mitigations. [...]
Academic researchers developed a new side-channel attack called SLAM that exploits hardware features designed to improve security in upcoming CPUs from Intel, AMD, and Arm to obtain the root password hash from the kernel memory. [...]
Security researchers have discovered a new speculative execution attack called Retbleed that affects processors from both Intel and AMD and could be used to extract sensitive information. [...]
A new side-channel attack known as Hertzbleed allows remote attackers to steal full cryptographic keys by observing variations in CPU frequency enabled by dynamic voltage and frequency scaling (DVFS). [...]
