CVE-2017-15588 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry.
CVE-2017-15591 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen 4.5.x through 4.9.x allowing attackers (who control a stub domain kernel or tool stack) to cause a denial of service (host OS crash) because of a missing comparison (of range start to range end) within the DMOP map/unmap implementation.
CVE-2017-15595 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (unbounded recursion, stack consumption, and hypervisor crash) or possibly gain privileges via crafted page-table stacking.
CVE-2017-15596 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error.
CVE-2017-12137 3 Citrix, Debian, Xen 3 Xenserver, Debian Linux, Xen 2025-04-20 N/A
arch/x86/mm.c in Xen allows local PV guest OS users to gain host OS privileges via vectors related to map_grant_ref.
CVE-2017-10918 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x does not validate memory allocations during certain P2M operations, which allows guest OS users to obtain privileged host OS access, aka XSA-222.
CVE-2017-10921 1 Xen 1 Xen 2025-04-20 N/A
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.
CVE-2017-8904 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214.
CVE-2017-17045 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to gain privileges on the host OS, obtain sensitive information, or cause a denial of service (BUG and host OS crash) by leveraging the mishandling of Populate on Demand (PoD) Physical-to-Machine (P2M) errors.
CVE-2017-15594 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging.
CVE-2017-8903 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.8.x on 64-bit platforms mishandles page tables after an IRET hypercall, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-213.
CVE-2017-7995 3 Novell, Suse, Xen 6 Suse Linux Enterprise Point Of Sale, Suse Linux Enterprise Server, Manager and 3 more 2025-04-20 N/A
Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL.
CVE-2017-12135 3 Citrix, Debian, Xen 3 Xenserver, Debian Linux, Xen 2025-04-20 N/A
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.
CVE-2017-12134 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 N/A
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.
CVE-2017-12855 1 Xen 1 Xen 2025-04-20 N/A
Xen maintains the _GTF_{read,writ}ing 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 status bits too early, incorrectly informing the guest that the grant is no longer in use. A guest may prematurely believe that a granted frame is safely private again, and reuse it in a way which contains sensitive information, while the domain on the far end of the grant is still using the grant. Xen 4.9, 4.8, 4.7, 4.6, and 4.5 are affected.
CVE-2017-10920 1 Xen 1 Xen 2025-04-20 N/A
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.
CVE-2016-9385 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 N/A
The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks.
CVE-2016-9816 1 Xen 1 Xen 2025-04-20 N/A
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at EL2.
CVE-2017-15589 1 Xen 1 Xen 2025-04-20 N/A
An issue was discovered in Xen through 4.9.x allowing x86 HVM guest OS users to obtain sensitive information from the host OS (or an arbitrary guest OS) because intercepted I/O operations can cause a write of data from uninitialized hypervisor stack memory.
CVE-2016-9384 1 Xen 1 Xen 2025-04-20 N/A
Xen 4.7 allows local guest OS users to obtain sensitive host information by loading a 32-bit ELF symbol table.
