|---|---|---|---|---|
| CVE-2011-3346 | 3 Qemu, Redhat, Xen | 3 Qemu, Enterprise Linux, Xen | 2025-04-12 | N/A |
| Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command.

| Multiple integer overflows in the (1) FLASK_GETBOOL, (2) FLASK_SETBOOL, (3) FLASK_USER, and (4) FLASK_CONTEXT_TO_SID suboperations in the flask hypercall in Xen 4.3.x, 4.2.x, 4.1.x, 3.2.x, and earlier, when XSM is enabled, allow local users to cause a denial of service (processor fault) via unspecified vectors, a different vulnerability than CVE-2014-1892, CVE-2014-1893, and CVE-2014-1894. | ||||
| CVE-2016-7154 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in the FIFO event channel code in Xen 4.4.x allows local guest OS administrators to cause a denial of service (host crash) and possibly execute arbitrary code or obtain sensitive information via an invalid guest frame number. | ||||
| CVE-2016-6258 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
| The PV pagetable code in arch/x86/mm.c in Xen 4.7.x and earlier allows local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries. | ||||
| CVE-2016-4963 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| 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. | ||||
| CVE-2016-6259 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-12 | N/A |
| Xen 4.5.x through 4.7.x do not implement Supervisor Mode Access Prevention (SMAP) whitelisting in 32-bit exception and event delivery, which allows local 32-bit PV guest OS kernels to cause a denial of service (hypervisor and VM crash) by triggering a safety check. | ||||
| CVE-2015-5154 | 5 Fedoraproject, Qemu, Redhat and 2 more | 10 Fedora, Qemu, Enterprise Linux and 7 more | 2025-04-12 | N/A |
| Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. | ||||
| CVE-2016-3961 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | N/A |
| Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. | ||||
| CVE-2015-4164 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The compat_iret function in Xen 3.1 through 4.5 iterates the wrong way through a loop, which allows local 32-bit PV guest administrators to cause a denial of service (large loop and system hang) via a hypercall_iret call with EFLAGS.VM set. | ||||
| 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-2016-3960 | 3 Fedoraproject, Oracle, Xen | 3 Fedora, Vm Server, Xen | 2025-04-12 | N/A |
| Integer overflow in the x86 shadow pagetable code in Xen allows local guest OS users to cause a denial of service (host crash) or possibly gain privileges by shadowing a superpage mapping. | ||||
| CVE-2016-4480 | 2 Oracle, Xen | 2 Vm Server, Xen | 2025-04-12 | N/A |
| The guest_walk_tables function in arch/x86/mm/guest_walk.c in Xen 4.6.x and earlier does not properly handle the Page Size (PS) page table entry bit at the L4 and L3 page table levels, which might allow local guest OS users to gain privileges via a crafted mapping of memory. | ||||
| CVE-2015-5166 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2025-04-12 | N/A |
| Use-after-free vulnerability in QEMU in Xen 4.5.x and earlier does not completely unplug emulated block devices, which allows local HVM guest users to gain privileges by unplugging a block device twice. | ||||
| CVE-2015-5307 | 6 Canonical, Debian, Linux and 3 more | 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more | 2025-04-12 | N/A |
| The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c. | ||||
| CVE-2015-6654 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x, 4.4.x, and earlier does not limit the number of printk console messages when reporting a failure to retrieve a reference on a foreign page, which allows remote domains to cause a denial of service by leveraging permissions to map the memory of a foreign guest. | ||||
| CVE-2016-5242 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion. | ||||
| CVE-2015-7311 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| libxl in Xen 4.1.x through 4.6.x does not properly handle the readonly flag on disks when using the qemu-xen device model, which allows local guest users to write to a read-only disk image. | ||||
| CVE-2016-7092 | 1 Xen | 1 Xen | 2025-04-12 | N/A |
| The get_page_from_l3e function in arch/x86/mm.c in Xen allows local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables. | ||||
