CVE-2026-98468

A flaw was found in the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem for ARM64. This flaw may allow a local user to cause a Denial of Service (DoS) or kernel instability. A race condition occurs when virtual machine stage 2 memory tables are freed concurrently with host memory migration under memory compaction pressure. When this race occurs, the kernel encounters an unexpected return value during memory unmapping, triggering a spurious warning that can crash hosts configured to panic on warnings.
