This critical flaw affects numerous kernel versions for nearly a decade and can lead to guest-to-host escapes in virtualized environments.https://onurbaydas.com/en/news/2026-10-16-cloud-hypervisor-live-migration/Fri, 16 Oct 2026 00:17:33 +0300https://onurbaydas.com/en/news/2026-10-16-cloud-hypervisor-live-migration/Cloud Hypervisor 54, a Rust-based Virtual Machine Monitor (VMM), has been released with significant improvements in live migration features. This version specifically aims to enhance the seamless portability of virtual machines.https://onurbaydas.com/en/news/2026-10-16-linux-kernel-pwnescape-vm-host-memory/Fri, 16 Oct 2026 00:17:33 +0300https://onurbaydas.com/en/news/2026-10-16-linux-kernel-pwnescape-vm-host-memory/A newly discovered critical vulnerability in the Linux kernel allows code within virtual machines to read the memory of the host computer they run on. A researcher demonstrated this flaw against Vercel's live cloud sandboxes, and Vercel confirmed it.https://onurbaydas.com/en/news/2026-10-16-intel-nova-lake-sr-iov-xe-graphics/Fri, 16 Oct 2026 00:17:33 +0300https://onurbaydas.com/en/news/2026-10-16-intel-nova-lake-sr-iov-xe-graphics/A patch posted to the Linux kernel mailing list by an Intel engineer confirms that Nova Lake S and Nova Lake P processors will support SR-IOV with integrated Xe graphics. This is a significant development that will enhance graphics performance in virtualized environments.
