IPFire Hardened Linux Firewall Distro Is Now Powered by Linux Kernel 6.1 LTS

IPFire project’s Peter Müller announced today the release and general availability of IPFire 2.27 Core Update 173 as the first update to this open-source hardened Linux firewall distribution for routers and firewalls in 2023. 

Powered by the long-term supported Linux 6.1 LTS kernel series, IPFire 2.27 Core Update 173 is here to introduce support for the QMI (Qualcomm MSM Interface) a proprietary interface and the ability to interact with 4G and 5G modems that use the QMI interface.

The new Linux 6.1 LTS kernel brings improved hardware support and security improvements for IPFire users, such as Landlock support, protection against direct memory access via malicious PCI devices on AArch64 (ARM64) systems, protection against cold boot attacks by allowing the firmware to wipe all memory when rebooting, and much more.
