CVE-2017-10914

CVE-2017-10914 affects Xen (grant-table feature) through 4.8.x due to a race condition in grant handling that can cause a double free. Impact includes denial of service (memory consumption) and potential information disclosure or privilege escalation. Based on the sources, exploitability depends ...

CVE-2017-10922

CVE-2017-10922 affects Xen’s grant-table feature. The grant-table MMIO region grant references are mishandled in Xen up to 4.8.x, enabling guest OS users to cause a denial of service (loss of grant trackability). This is part of XSA-224 (bug 3). Documented impact is a DoS; no exploitation method ...

CVE-2017-10913

The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1...

CVE-2017-10912

Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217...

CVE-2017-10914

The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service memory consumption, or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2...

CVE-2017-10913

CVE-2017-10923

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...

CVE-2017-10920

The grant-table feature in Xen through 4.8.x mishandles a GNTMAPdevicemap and GNTMAPhostmap mapping, when followed by only a GNTMAPhostmap 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...

CVE-2017-10923

CVE-2017-10923 affects the Xen hypervisor (Xen 4.8.x and earlier). The root cause is a missing validation of the vCPU array index when an SGI is sent, which can allow a guest OS user to trigger a denial of service resulting in a hypervisor crash (XSA-225). The connected documents describe this as...

CVE-2017-10920

CVE-2017-10920 affects Xen up to 4.8.x, where grant-table GNTMAP_device_map and GNTMAP_host_map handling is flawed. If followed by only a GNTMAP_host_map unmapping, guest OS users can cause a denial of service (count mismanagement, memory corruption) or obtain privileged host OS access (XSA-224 b...

CVE-2017-10919

CVE-2017-10919 affects the Xen hypervisor (up to 4.8.x) due to incorrect handling of virtual interrupt injection on ARM, allowing denial of service (hypervisor crash) for guest OS users. Connected documents confirm mitigations in package updates: Debian’s DSA-3969-1 fixes CVE-2017-10919 in Xen 4....
