8.8
2017-08-24 CVE-2017-12136 Race Condition vulnerability in multiple products
Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling.

high complexity
xen citrix debian CWE-362
7.8
2017-08-24 CVE-2017-12135 Incorrect Calculation vulnerability in multiple products
Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants.

low complexity
xen citrix debian CWE-682
8.8
2017-08-24 CVE-2017-12134 Incorrect Calculation vulnerability in multiple products
The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.

2017-08-15 CVE-2017-12855 Information Exposure vulnerability in XEN
Xen maintains the _GTF_{read,writ}ing bits as appropriate, to inform the guest that a grant is in use.
local
low complexity
xen CWE-200
6.5
2017-07-05 CVE-2017-10923 Improper Input Validation vulnerability in XEN
Xen through 4.8.x does not validate a vCPU array index upon the sending of an SGI, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-225.

low complexity
xen CWE-20
6.5
2017-07-05 CVE-2017-10922 Resource Exhaustion vulnerability in XEN
The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3.
network
low complexity
xen CWE-400
7.5
2017-07-05 CVE-2017-10921 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN
The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2.

2017-07-05 CVE-2017-10920 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in XEN
The grant-table feature in Xen through 4.8.x mishandles a GNTMAP_device_map and GNTMAP_host_map mapping, when followed by only a GNTMAP_host_map unmapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 1.
