Loading vulnerability…
CVE-2025-22013 is a state-management flaw in Linux kernel KVM for arm64. Hypervisor code lazily saved the host FPSIMD/SVE/SME context while loading a virtual CPU. Inconsistent handling of host SVE enablement state could discard host SVE state; ptrace-modified SVE state could subsequently be discarded; and host FPMR state could remain stale when a non-protected VM that uses FPSIMD/SVE did not expose FPMR. The fix eagerly saves and flushes host FPSIMD/SVE/SME state during vCPU FP-state loading, preventing KVM from later relying on lazy preservation of host state.
