Red Hat Security Advisory 2021-2763-01 - Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. The kernel packages contain the Linux kernel, the core of any Linux operating system. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Ansible is a SSH-based configuration management, deployment, and task execution system. The openshift-ansible packages contain Ansible code and playbooks for installing and upgrading OpenShift Container Platform 3.

Qualys discovered a size_t-to-int conversion vulnerability in the Linux kernel's filesystem layer: by creating, mounting, and deleting a deep directory structure whose total path length exceeds 1GB, an unprivileged local attacker can write the 10-byte string "//deleted" to an offset of exactly -2GB-10B below the beginning of a vmalloc()ated kernel buffer. They successfully exploited this uncontrolled out-of-bounds write, and obtained full root privileges on default installations of Ubuntu 20.04, Ubuntu 20.10, Ubuntu 21.04, Debian 11, and Fedora 34 Workstation; other Linux distributions are certainly vulnerable, and probably exploitable. A basic proof of concept (a crasher) is attached to this advisory.
