Free architecture meets free OS. AlmaLinux OS Kitten 10 is now available for RISC-V, because open hardware deserves open software! 🙌 https://almalinux.org/blog/2026-03-17-almalinux-goes-riscv/

AlmaLinux goes RISC-V: Kitten 10 now available for riscv64

RISC-V is a free and open instruction set architecture (ISA) based on RISC principles. Unlike proprietary ISAs such as x86 or ARM, the RISC-V specification is openly available, allowing anyone to implement it without licensing fees. Hardware platforms based on RISC-V are becoming more widely available, from microcontrollers to application-class processors capable of running full Linux distributions. We are excited to announce that AlmaLinux OS Kitten 10 is now available for the RISC-V architectu

📢 An unprivileged user inside a container can use this new Linux kernel local-privilege-escalation flaw, IPV6_FRAG_ESCAPE, to escape to a root shell on the host. The vulnerable code path lives in the 6.12 kernel, which means only AlmaLinux 10 and Kitten 10 are affected. Help us test the patched kernels: https://almalinux.org/blog/2026-06-30-ipv6-frag-escape/
