https://utube.ro/videos/watch/c9904394-93e7-465c-91b8-7b09c90eb781 A nine-year-old bug in the Linux kernel is now being actively exploited in the wild. CVE-2026-31431 (Copy Fail) gives any unprivileged local user a root shell on essentially every Linux distribution built since 2017. It leaves no trace on disk. CISA confirmed active exploitation on May 5th and ordered federal agencies to patch by May 15th. This video covers what it is, how bad it actually is, the broken mitigation that's given many systems false confidence, and the patch status for every major distribution including Proxmox. 🔗 Blog post with all commands: https://dbtechreviews.com/2026/05/06/cve-2026-31431-copy-fail-the-linux-vulnerability-being-actively-exploited-right-now/ ⏱ CHAPTERS 00:00 - What Is Copy Fail? 01:03 - How the Exploit Works 01:52 - How Bad Is It Really? 02:53 - CISA Confirms Active Exploitation 03:04 - The Broken Mitigation 04:07 - The Correct Fix for RHEL-Family Systems 04:52 - Patch Status: Debian, Ubuntu, AlmaLinux, Fedora, SUSE 05:08 - Patch Status: RHEL and Proxmox 05:26 - Blog Post with Commands 05:39 - The AI Angle 06:33 - Action Items 🔗 LINKS & SOURCES Xint: Copy Fail technical disclosure: https://xint.io/blog/copy-fail-linux-distributions Help Net Security: CopyFail nine-year Linux kernel flaw: https://www.helpnetsecurity.com/2026/04/30/copyfail-linux-lpe-vulnerability-cve-2026-31431/ Microsoft Security Blog: CVE-2026-31431 Copy Fail: https://www.microsoft.com/en-us/security/blog/2026/05/01/cve-2026-31431-copy-fail-vulnerability-enables-linux-root-privilege-escalation/ CISA Known Exploited Vulnerabilities catalog: https://www.cisa.gov/known-exploited-vulnerabilities-catalog CloudLinux: broken mitigation warning: https://blog.cloudlinux.com/cve-2026-31431-copy-fail-kernel-update AlmaLinux: Copy Fail patch announcement: https://almalinux.org/blog/2026-05-01-cve-2026-31431-copy-fail/ CERT-EU: Copy Fail advisory: https://cert.europa.eu/publications/security-advisories/2026-005/ The Hacker News: CISA adds CopyFail to KEV: https://thehackernews.com/2026/05/cisa-adds-actively-exploited-linux-root.html Bugcrowd: What we know about Copy Fail: https://www.bugcrowd.com/blog/what-we-know-about-copy-fail-cve-2026-31431/ Debian security tracker: CVE-2026-31431: https://security-tracker.debian.org/tracker/CVE-2026-31431 OSTechNix: Debian patched Copy Fail: https://ostechnix.com/debian-13-trixie-copy-fail-cve-2026-31431-vulnerability-fix/ The Register: CopyFail attackers cashing in: https://www.theregister.com/security/2026/05/05/copyfail-attackers-start-cashing-in-on-linux-flaw/ 🔗 Blog post with all commands: https://dbtechreviews.com/2026/05/06/cve-2026-31431-copy-fail-the-linux-vulnerability-being-actively-exploited-right-now/ /=========================================/ ✅ Amazon Wishlist: https://dbte.ch/amznwishlist Get early, ad-free access to new content by becoming a channel member, or a Patron! ✅ https://www.patreon.com/dbtech ✅ https://www.youtube.com/channel/UCVy16RS5eEDh8anP8j94G2A/join All My Social Links: ✅ https://dbt3.ch/@dbtech Join Discord! ✅ https://discord.gg/M9J6hFq /=========================================/ ✨Ways to support DB Tech: ✅ https://www.patreon.com/dbtech ✅ https://www.paypal.me/DBTechReviews ✅ https://ko-fi.com/dbtech ✅ Cashapp: https://cash.app/$dbtechyt ✅ Venmo: https://venmo.com/dbtechyt ✨Come chat in Discord: ✅ https://dbte.ch/discord Thu, 07 May 2026 17:40:19 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://utube.ro https://utube.ro/lazy-static/avatars/888f68a5-dd7d-4b7f-b73d-9e288452fcb8.png https://utube.ro/videos/watch/c9904394-93e7-465c-91b8-7b09c90eb781 All rights reserved, unless otherwise specified in the terms specified at https://utube.ro/about and potential licenses granted by each content's rightholder.
