teardown ordering

The teardown ordering tag on WindowsForum.com covers a specific kernel-level vulnerability (CVE-2025-23135) in RISC-V KVM where the module removal sequence executes architecture-specific cleanup routines in the wrong order. This ordering bug leaves per-CPU IRQ state inconsistent, prevents the KVM module from being reinserted without a host reboot, and can cause kernel oopses during module removal. The issue is an availability and correctness problem rather than a memory corruption or data exfiltration risk. Discussions focus on the upstream patch, affected hosts, and tracking across vulnerability databases. The tag is relevant for enterprise IT and security professionals managing RISC-V virtualization environments.
