We lost one of the greats of stage and screen today. And, in my book, a tremendous friend and man. I learned so much from him. I will miss you, Patrick Stewart, all of my days. @mang0ld
‼️ Linux Kernel Flaw Lets Attackers Escape Virtual Machines and Take Control of Hosts
Details: https://t.co/znWU0Rtebz
A critical flaw in the Linux kernel may allow an attacker-controlled virtual machine (VM) to breach its isolation boundary and impact the host system. Paulos Yibelo demonstrated a technique that exposes host memory and, in their lab, progressed to host-level code execution.
The flaw is serious for cloud providers and organizations that run untrusted workloads in virtual machines. VM isolation is meant to stop code inside one guest from reaching the host and other workloads.
PwnEscape shows how a weakness in a host’s packet-processing path can threaten that boundary, even when the underlying issue is not in the hypervisor itself.
