  "description": "In the Linux kernel, the following vulnerability has been resolved:  KVM: s390: Fix _gaccess_shadow_fault()  In some circumstances, it is possible that the page of nested guest memory that is being shadowed is not present at all in the parent guest gmap. dat_entry_walk() will not find any leaf entry and return with -ENOENT, which will erroneously be propagated all the way to userspace.  Fix by manually calling gmap_link() on the memory of the nested guest that is being shadowed if the mapping was not already present.",
