An attacker could theoretically exploit this by triggering concurrent grant table operations (via gnttab_map_refs() and gnttab_unmap_refs()) that lead to incorrect or inconsistent memory mappings, potentially causing memory corruption or denial of service. However, due to the extremely rare occurrence and limited impact in real-world use
