Xen Security Advisory 519 v2 (CVE-2026-102699,CVE-2026-102702) - Arm: multiple issues with GNTTABOP_cache_flush

Xen published Security Advisory 519 version 2, addressing multiple issues with the GNTTABOP_cache_flush operation on Arm systems through CVE-2026-102699 and CVE-2026-102702. The advisory represents a public release following a prior fix from XSA-437 that addressed cache flush overflow calculations.

Why it matters: Xen hypervisor operators running Arm-based systems should review this advisory to determine if patches are available and applicable to their deployments, as the vulnerabilities affect guest-initiated cache flush operations.
