About this tag
The kvm riscv tag on WindowsForum.com covers discussions about the KVM (Kernel-based Virtual Machine) implementation for RISC-V architecture. Recent content includes a thread on CVE-2025-23135, a vulnerability in the RISC-V KVM teardown sequence that causes an ordering bug during module removal. This bug can leave per-CPU IRQ state inconsistent, preventing KVM module reinsertion without a host reboot and potentially causing kernel oopses. The issue is an availability and correctness problem, not a memory corruption or data exfiltration risk. The tag focuses on security patches, bug fixes, and technical details of KVM on RISC-V, relevant to developers and system administrators working with this virtualization platform.
