Critical PwnEscape Linux Kernel Vulnerability Lets Guest VMs Read Host Memory
A newly disclosed critical flaw in the Linux kernel allows code inside a virtual machine to read memory on the host computer it runs on. A researcher demonstrated the leak against Vercel's live cloud sandboxes, and Vercel confirmed it. The flaw, now tracked as CVE-2026-99999 and nicknamed PwnEscape, is in the Linux kernel's networking code, not in any one cloud's setup, so it reaches the shared
