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

AWS Security Agent (now part of AWS Continuum) exploited 33 of 37 new real-world CVEs

We applied AWS Security Agent (now part of AWS Continuum), our autonomous penetration-testing agent, to 37 real, recently disclosed Common Vulnerabilities and Exposures (CVEs), each packaged as a live, containerized target with a flag hidden at the vulnerability’s intended sink. Starting from an unauthenticated or low-privilege position (an endpoint URL and a one-line hint, no […]

Vulnerability Management Isn't About the Score — It's About How It Applies to You

NGINX Fixes 5 Flaws, Including Possible RCE and a TLS Bug That May Skip Client-Cert Checks

NGINX released versions 1.30.6 and 1.31.7 on October 14 to fix five vulnerabilities, one of them present in every release since May 2005. There are three memory bugs that F5, the company behind NGINX, says could crash a worker process or possibly let an attacker run code, and each requires a specific configuration to exploit. A fourth lets an attacker forge a TLS session that could

Next.js Ships Out-of-Band Patch for Two Critical RCE Flaws in Caching and SVG Processing

Next.js released an out-of-band security update on October 14 that fixes two critical flaws allowing unauthenticated remote code execution, along with a high-severity denial-of-service flaw.

Drupal Patches Critical Field UI Flaw With Unauthenticated RCE Path via Contributed Modules

Drupal core has a critical flaw in its Field UI module that could let an attacker run code on the site's server, and fixes were shipped on October 14 in Drupal 11.4.10, 11.3.19, and 10.6.19. An attacker cannot reach the flaw through core alone, the Drupal Security Team said in its advisory. Several exploit paths exist through contributed modules, and at least one known path needs no login.
