Upstream information

CVE-2026-62428 at MITRE

Description

When grant-copy operations are processed, the respective grant may or may
not already be in use by another operation (a mapping or another copy).
For all copy operations the referenced guest frame is looked up. When
another operation is already active for the grant (the grant is "pinned"),
what is being supplied back to actually carry out permission checks and
copy operation may not be consistent: The permission check may be carried
out on a page different from the one involved in the copy.

Note from the SUSE Security Team on the xen package

This issue likely only affects the XEN hypervisor itself, unless otherwise stated. The userland utilities in -tools and libraries in -libs are shipped together with the xen hypervisor as they are built from one source and do not contain hypervisor specific fixes.
