About this tag
CVE-2025-37849 is a Linux host-side KVM vulnerability affecting Arm64 systems, not a Windows flaw. The issue involves KVM failing to clean up virtual GIC state after a failed virtual CPU creation, which can lead to a use-after-free during later redistributor operations. The upstream fix addresses this cleanup. The CVE was assigned by kernel.org on May 9, 2025, and recent NVD updates may cause confusion about its publication date, but it is not a newly discovered bug. For Windows users, this CVE has no direct impact, but it is relevant for those managing Linux KVM hosts on Arm64 hardware.
