"PwnEscape" is the KVM escape for which rumors made the rounds a few days ago. Getting CVE-2026-99999 assigned is 👨🏻🍳💋.
Kernel patch for this part (because it sounds like there's multiple):
https://github.com/torvalds/linux/commit/6785011f8b16abf40b1e9d8b2e332232b3e68822
Security researchers have disclosed PwnEscape (CVE-2026-99999), a vulnerability in the Linux kernel networking subsystem.
The flaw enables a virtual machine to access memory belonging to the host, with potential for system crashes or arbitrary code execution.
It was discovered by using AI-assisted analysis during a Vercel competition.
Patches are included in recent stable kernel releases, such as 5.10.272 and 6.12.113.

‼️ A newly disclosed critical Linux kernel flaw, PwnEscape (CVE-2026-99999), lets code inside guest VMs read host memory and enabled VM escape with root access in lab tests.
Read - https://thehackernews.com/2026/10/critical-pwnescape-linux-kernel.html
Vercel confirmed the memory leak in its live production sandboxes during its $1 million security challenge.
The flaw lies in Linux networking, not the hypervisor, with implications beyond Vercel.
Critical PwnEscape Linux Kernel Vulnerability Lets Guest VMs Read Host Memory
A critical flaw in the Linux kernel’s networking code (CVE-2026-99999, nicknamed PwnEscape) lets code inside a virtual machine read host memory, crash the host, or run code on it, The Hacker News reports. The flaw was found through a Vercel security challenge and demonstrated against Vercel’s live cloud sandboxes; there is no sign it has been used in a real attack. https://thehackernews.com/2026/10/critical-pwnescape-linux-kernel.html
