Description
This record describes two related vulnerabilities in the Xen hypervisor's grant copy operations. The vulnerabilities involve incorrect internal caching and validation of grant references and frame numbers during batch copy operations on adjacent memory ranges. Specifically, CVE-2026-102703 concerns mixing up frame numbers and grant references, while CVE-2026-102704 involves a misplaced check that allows copying by frame number beyond the caller's own memory.
