Description
This record describes two related vulnerabilities in Xen's grant copy operations involving incorrect validation of cached data. One issue (CVE-2026-102703) involves mixing up frame numbers and grant references. The other (CVE-2026-102704) concerns a misplaced check that allows copying by frame number beyond the caller's own memory, violating intended restrictions.
