Linux security updates Week 3, 2026

Here are the Linux security updates for Week 3, 2026:

AlmaLinux, Debian, Fedora, Oracle, Red Hat Enterprise Linux, Rocky Linux, Slackware, SUSE, and Ubuntu released security updates for core components including GNU tar, Ruby, Linux kernel, Mozilla Thunderbird, GIMP, Adminer, curl, ImageMagick, Chromium, MariaDB, libpng, and pki-servlet-engine.

Fedora 42/43 shipped fixes for gnupg2, proxychains-ng, libpcap, python-pdfminer, libsodium, wasmedge, nginx, SeaMonkey, MariaDB, and others, addressing issues like remote code execution and denial-of-service in networking and web-related stacks.

Slackware published updates for libsodium, curl, libtasn1, and lcms2 to resolve problems including insufficient validation, OpenSSL bypass, stack-based buffer overflows, and heap buffer overflows, while SUSE pushed more than 100 vulnerability fixes across packages such as Python312-Django6, Xen, pgAdmin4, Buildah, kernel, dcmtk, and rsync.

These Week patches focus on memory safety bugs, input validation issues, and remote code execution vectors in widely deployed tools, so keeping systems updated is critical.
