CopyFail Linux Vulnerability Enables Root Access Exploits
Researchers from Theori released exploit code for CVE-2026-31431, known as CopyFail, a serious local privilege escalation flaw affecting most Linux releases. The single Python script works across distributions like Ubuntu 22.04, Amazon Linux 2023, SUSE 15.6, and Debian 12, threatening multi-tenant servers, Kubernetes containers, and CI/CD pipelines. Kernel patches exist for versions including 7.0, 6.19.12, and others, but many distributions lack updates, prompting urgent checks.
