Here are the Linux security updates for the last week of December 2025 (Week 52, 2025):
AlmaLinux, Debian, Fedora, Oracle, Red Hat Enterprise Linux, Rocky Linux, Slackware, and SUSE released security updates for key packages including binutils, curl, Chromium, PHP, PostgreSQL, git-lfs, libssh, openssh, opentelemetry-collector, kernel, webkit2gtk3, mod_md, grafana, httpd, podman, skopeo, python3.12, and python39.
Debian LTS issued fixes for openjpeg2, kodi, pgbouncer, python-urllib3, postgresql-13, and gst-plugins-good1.0 among late-December advisories.
Red Hat and Rocky Linux highlighted important-rated updates for kernel, keylime, httpd:2.4, and container-tools, alongside moderate ones for libssh and binutils.
These patches address vulnerabilities like remote code execution, denial-of-service, buffer overflows, and security bypasses in web engines, databases, and infrastructure tools.
