The product enables different and incompatible operating systems to run on the same computer and supports runtime migration to ensure uptime and avoid downtime. A security vulnerability exists in X...

Null pointer dereference

An issue was discovered in Xen 4.5.x through 4.9.x. The function gnttabcacheflush handles GNTTABOPcacheflush grant table operations. It checks to see if the calling domain is the owner of the page that is to be operated on. If it is not, the owner's grant table is checked to see if a grant mappin...

CVE-2017-14318

CVE-2017-14318 affects Xen 4.5.x–4.9.x. The vulnerability arises in __gnttab_cache_flush: when operating on a page owned by special domains (DOMID_XEN/IO/COW) that lack a grant table, the code may dereference a NULL pointer since it does not verify the owner’s grant table existence. This can enab...

CVE-2017-14319

A grant unmapping issue was discovered in Xen through 4.9.x. When removing or replacing a grant mapping, the x86 PV specific path needs to make sure page table entries remain in sync with other accounting done. Although the identity of the page frame was validated correctly, neither the presence ...

CVE-2017-12855

Xen maintains the GTFread,writing bits as appropriate, to inform the guest that a grant is in use. A guest is expected not to modify the grant details while it is in use, whereas the guest is free to modify/reuse the grant entry when it is not in use. Under some circumstances, Xen will clear the...
