CERT Polska disclosed two vulnerabilities in GNU coreutils, tracked as CVE-2026-56391 and CVE-2026-56392. The notice identifies the flaws as affecting the widely used GNU core utilities package, a foundational component on many Linux and Unix-like systems, and indicates the issues were reported to CERT Polska for publication.
Public reporting on the vulnerabilities remains limited, with the available references providing only the identifiers and confirming that two separate flaws were documented. No technical root cause, affected version range, exploitation details, or mitigation guidance were included in the cited notices, leaving organizations that rely on GNU coreutils to monitor vendor and CERT updates for patch and exposure information.

CERT Polska disclosed four vulnerabilities in **GNU gawk**, tracked as `CVE-2026-40467`, `CVE-2026-40468`, `CVE-2026-40469`, and `CVE-2026-40553`. The issues were highlighted in a CERT Polska advisory and later amplified by security reporting, identifying the widely used pattern-scanning and text-processing utility as affected software. Public reporting provides only limited detail so far, with no technical breakdown, exploitation evidence, or impact assessment included in the referenced notices. Organizations using GNU gawk should review the CERT Polska advisory, identify affected deployments, and prioritize vendor guidance or updates as more remediation details become available.

An `oss-sec` disclosure reported that the Rust-based **uutils coreutils** project contains **113 audit findings**, including **44 assigned CVEs** (`CVE-2026-35338` through `CVE-2026-35381`), after a Zellic review tied to Canonical's evaluation of the package for Ubuntu 26.04. Canonical said most issues had been resolved, but the report said multiple vulnerabilities were still reproducible on a fully updated Ubuntu 26.04 system running uutils coreutils `0.8.0`. Because of **TOCTOU race conditions**, Canonical kept the GNU implementations of `cp`, `mv`, and `rm` rather than replacing them with uutils versions. The published issues span `mkfifo`, `nohup`, `tail`, and other utilities, and include **symlink attacks, unsafe file creation, permission and ownership handling flaws, incorrect exit codes, UTF-8 parsing bugs, and logic errors** that could enable privilege escalation, information disclosure, denial of service, data corruption, or destructive filesystem operations. A follow-up `oss-sec` reply focused on the `mkfifo` case, agreeing that the race condition remained valid while clarifying that the example's initial FIFO permissions would be shaped by `umask(002)`, producing mode `664` rather than `666` before a later `chmod(2)` call.

CERT Polska disclosed three vulnerabilities in **GNU cpio** affecting versions through **2.15**, tracked as `CVE-2026-66484`, `CVE-2026-66485`, and `CVE-2026-66486`. The issues were reported by researchers from the **AFINE Team** and include a **path traversal** flaw during tar extraction, an **uncontrolled memory allocation** bug that can trigger **stack overflow** and **denial of service**, and an **improper output escaping** weakness. The output-handling flaw can allow **forged archive listings** or **terminal escape-sequence injection**, creating opportunities to mislead users or manipulate terminal output. CERT Polska said the vulnerabilities have been addressed in specific upstream commits, while a separate security notice amplified the disclosure and directed users to the CERT advisory for details on the affected GNU cpio software.
