NetBSD 11.1

NetBSD 11.1 is the first point release in the NetBSD 11 stable series, announced November 2, 2026. Its main purpose is to deliver security fixes and resolve bugs quickly rather than introduce broad new features. Existing users can upgrade by booting an installation image and choosing the upgrade option; those updating by other methods should install the kernel and modules first, reboot, and then update userland. The release supplies downloadable images and signed checksums, with binary distributions spanning dozens of architectures, from amd64, Arm, and RISC-V to legacy systems such as VAX, Atari, and Commodore Amiga.

Changes address problems across hardware ports, the kernel, drivers, build tools, and user programs. Notable fixes include crashes on newer VIA/Zhaoxin processors, Raspberry Pi USB instability, kernel race conditions and network-filter vulnerabilities, RAID reconstruction and SAS controller issues, and panics triggered by hotplugging USB Wi-Fi devices. Build improvements cover Apple Silicon cross-compilation and parallel debug-data generation; library fixes include printf formatting and unusual memchr arguments. Security-related third-party updates include OpenSSH 10.6, Unbound 1.26.1, updated X.Org components, a Brotli fix for a CVE, and replacement of compromised root certificates. NetBSD remains a freely licensed, portable Unix-like system intended for servers, desktops, research, and embedded devices, with applications available through pkgsrc.
