1 CVE-2019-17347 20 DoS +Priv 2019-10-07 2019-10-10
4.6
None Local Low Not required Partial Partial Partial
An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges because a guest can manipulate its virtualised %cr4 in a way that is incompatible with Linux (and possibly other guest kernels).
2 CVE-2019-17340 20 DoS +Priv 2019-10-07 2019-10-10
6.1
None Local Low Not required Partial Partial Complete
An issue was discovered in Xen through 4.11.x allowing x86 guest OS users to cause a denial of service or gain privileges because grant-table transfer requests are mishandled.
3 CVE-2017-14431 772 DoS 2017-09-13 2019-10-02
4.9
None Local Low Not required None None Complete
Memory leak in Xen 3.3 through 4.8.x allows guest OS users to cause a denial of service (ARM or x86 AMD host OS memory consumption) by continually rebooting, because certain cleanup is skipped if no pass-through device was ever assigned, aka XSA-207.
4 CVE-2016-9932 200 +Info 2017-01-26 2017-11-03
2.1
None Local Low Not required Partial None None
CMPXCHG8B emulation in Xen 3.3.x through 4.7.x on x86 systems allows local HVM guest OS users to obtain sensitive information from host stack memory via a "supposedly-ignored" operand size prefix.
5 CVE-2016-4963 284 DoS 2016-06-07 2018-09-07
1.9
None Local Medium Not required None None Partial
The libxl device-handling in Xen through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (management tool confusion) by manipulating information in the backend directories in xenstore.
6 CVE-2016-1571 17 DoS 2016-01-22 2018-10-30
4.7
None Local Medium Not required None None Complete
The paging_invlpg function in include/asm-x86/paging.h in Xen 3.3.x through 4.6.x, when using shadow mode paging or nested virtualization is enabled, allows local HVM guest users to cause a denial of service (host crash) via a non-canonical guest address in an INVVPID instruction, which triggers a hypervisor bug check.
7 CVE-2016-1570 20 DoS +Priv +Info 2016-01-22 2018-10-30
6.9
None Local Medium Not required Complete Complete Complete
The PV superpage functionality in arch/x86/mm.c in Xen 3.4.0, 3.4.1, and 4.1.x through 4.6.x allows local PV guests to obtain sensitive information, cause a denial of service, gain privileges, or have unspecified other impact via a crafted page identifier (MFN) to the (1) MMUEXT_MARK_SUPER or (2) MMUEXT_UNMARK_SUPER sub-op in the HYPERVISOR_mmuext_op hypercall or (3) unknown vectors related to page table updates.
8 CVE-2015-8552 20 DoS 2016-04-13 2017-11-03
1.7
None Local Low Single system None None Partial
The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka "Linux pciback missing sanity checks."
9 CVE-2015-8341 399 DoS 2015-12-17 2017-06-30
7.8
None Remote Low Not required None None Complete
The libxl toolstack library in Xen 4.1.x through 4.6.x does not properly release mappings of files used as kernels and initial ramdisks when managing multiple domains in the same process, which allows attackers to cause a denial of service (memory and disk consumption) by starting domains.
10 CVE-2015-8340 17 DoS 2015-12-17 2017-06-30
4.7
None Local Medium Not required None None Complete
The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly release locks, which might allow guest OS administrators to cause a denial of service (deadlock or host crash) via unspecified vectors, related to XENMEM_exchange error handling.
11 CVE-2015-8339 19 DoS 2015-12-17 2017-06-30
4.7
None Local Medium Not required None None Complete
The memory_exchange function in common/memory.c in Xen 3.2.x through 4.6.x does not properly hand back pages to a domain, which might allow guest OS administrators to cause a denial of service (host crash) via unspecified vectors related to domain teardown.
