CVE-2015-2044 1 Xen 1 Xen 2025-04-12 N/A
The emulation routines for unspecified X86 devices in Xen 3.2.x through 4.5.x does not properly initialize data, which allow local HVM guest users to obtain sensitive information via vectors involving an unsupported access size.
CVE-2015-0268 1 Xen 1 Xen 2025-04-12 N/A
The vgic_v2_to_sgi function in arch/arm/vgic-v2.c in Xen 4.5.x, when running on ARM hardware with general interrupt controller (GIC) version 2, allows local guest users to cause a denial of service (host crash) by writing an invalid value to the GICD.SGIR register.
CVE-2015-3456 3 Qemu, Redhat, Xen 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more 2025-04-12 N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2014-7156 1 Xen 1 Xen 2025-04-12 N/A
The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 3.3.x through 4.4.x does not check the supervisor mode permissions for instructions that generate software interrupts, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors.
CVE-2014-6268 1 Xen 1 Xen 2025-04-12 N/A
The evtchn_fifo_set_pending function in Xen 4.4.x allows local guest users to cause a denial of service (host crash) via vectors involving an uninitialized FIFO-based event channel control block when (1) binding or (2) moving an event to a different VCPU.
CVE-2015-4163 1 Xen 1 Xen 2025-04-12 N/A
GNTTABOP_swap_grant_ref in Xen 4.2 through 4.5 does not check the grant table operation version, which allows local guest domains to cause a denial of service (NULL pointer dereference) via a hypercall without a GNTTABOP_setup_table or GNTTABOP_set_version.
CVE-2014-5147 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service (host crash) via a crafted 32-bit process.
CVE-2014-4022 1 Xen 1 Xen 2025-04-12 N/A
The alloc_domain_struct function in arch/arm/domain.c in Xen 4.4.x, when running on an ARM platform, does not properly initialize the structure containing the grant table pages for a domain, which allows local guest administrators to obtain sensitive information via the GNTTABOP_setup_table subhypercall.
CVE-2014-4021 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-12 N/A
Xen 3.2.x through 4.4.x does not properly clean memory pages recovered from guests, which allows local guest OS users to obtain sensitive information via unspecified vectors.
CVE-2014-3969 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x, when running on an ARM system, does not properly check write permissions on virtual addresses, which allows local guest administrators to gain privileges via unspecified vectors.
CVE-2015-2045 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2025-04-12 N/A
The HYPERVISOR_xen_version hypercall in Xen 3.2.x through 4.5.x does not properly initialize data structures, which allows local guest users to obtain sensitive information via unspecified vectors.
CVE-2014-3716 1 Xen 1 Xen 2025-04-12 N/A
Xen 4.4.x does not properly check alignment, which allows local users to cause a denial of service (crash) via an unspecified field in a DTB header in a 32-bit guest kernel.
CVE-2014-3715 1 Xen 1 Xen 2025-04-12 N/A
Buffer overflow in Xen 4.4.x allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit guest kernel, related to searching for an appended DTB.
CVE-2014-3714 1 Xen 1 Xen 2025-04-12 N/A
The ARM image loading functionality in Xen 4.4.x does not properly validate kernel length, which allows local users to read system memory or cause a denial of service (crash) via a crafted 32-bit ARM guest kernel in an image, which triggers a buffer overflow.
CVE-2014-2599 1 Xen 1 Xen 2025-04-12 N/A
The HVMOP_set_mem_access HVM control operations in Xen 4.1.x for 32-bit and 4.1.x through 4.4.x for 64-bit allow local guest administrators to cause a denial of service (CPU consumption) by leveraging access to certain service domains for HVM guests and a large input.
CVE-2014-2580 1 Xen 1 Xen 2025-04-12 N/A
The netback driver in Xen, when using certain Linux versions that do not allow sleeping in softirq context, allows local guest administrators to cause a denial of service ("scheduling while atomic" error and host crash) via a malformed packet, which causes a mutex to be taken when trying to disable the interface.
CVE-2014-7188 1 Xen 1 Xen 2025-04-12 N/A
The hvm_msr_read_intercept function in arch/x86/hvm/hvm.c in Xen 4.1 through 4.4.x uses an improper MSR range for x2APIC emulation, which allows local HVM guests to cause a denial of service (host crash) or read data from the hypervisor or other guests via unspecified vectors.
CVE-2014-1896 1 Xen 1 Xen 2025-04-12 N/A
The (1) do_send and (2) do_recv functions in io.c in libvchan in Xen 4.2.x, 4.3.x, and 4.4-RC series allows local guests to cause a denial of service or possibly gain privileges via crafted xenstore ring indexes, which triggers a "read or write past the end of the ring."
CVE-2014-7154 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Opensuse and 1 more 2025-04-12 N/A
Race condition in HVMOP_track_dirty_vram in Xen 4.0.0 through 4.4.x does not ensure possession of the guarding lock for dirty video RAM tracking, which allows certain local guest domains to cause a denial of service via unspecified vectors.
CVE-2014-3968 2 Opensuse, Xen 2 Opensuse, Xen 2025-04-12 N/A
The HVMOP_inject_msi function in Xen 4.2.x, 4.3.x, and 4.4.x allows local guest HVM administrators to cause a denial of service (host crash) via a large number of crafted requests, which trigger an error messages to be logged.
