| Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space." | ||||
| CVE-2011-2901 | 1 Xen | 1 Xen | 2023-02-13 | N/A |
| Off-by-one error in the __addr_ok macro in Xen 3.3 and earlier allows local 64 bit PV guest administrators to cause a denial of service (host crash) via unspecified hypercalls that ignore virtual-address bits. | ||||
| CVE-2015-7504 | 3 Debian, Qemu, Xen | 3 Debian Linux, Qemu, Xen | 2023-02-13 | 8.8 High |
| Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. | ||||

| The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. | ||||
| CVE-2015-5154 | 4 Fedoraproject, Qemu, Suse and 1 more | 8 Fedora, Qemu, Linux Enterprise Debuginfo and 5 more | 2023-02-13 | 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-2014-3672 | 2 Redhat, Xen | 2 Libvirt, Xen | 2023-02-13 | N/A |
| The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. | ||||
| CVE-2013-4355 | 1 Xen | 1 Xen | 2023-02-13 | N/A |
| Xen 4.3.x and earlier does not properly handle certain errors, which allows local HVM guests to obtain hypervisor stack memory via a (1) port or (2) memory mapped I/O write or (3) other unspecified operations related to addresses without associated memory. | ||||
| CVE-2013-0215 | 1 Xen | 1 Xen | 2023-02-13 | N/A |
| oxenstored in Xen 4.1.x, Xen 4.2.x, and xen-unstable does not properly consider the state of the Xenstore ring during read operations, which allows guest OS users to cause a denial of service (daemon crash and host-control outage, or memory consumption) or obtain sensitive control-plane data by leveraging guest administrative access. | ||||
| CVE-2012-5513 | 1 Xen | 1 Xen | 2023-02-13 | N/A |
| The XENMEM_exchange handler in Xen 4.2 and earlier does not properly check the memory address, which allows local PV guest OS administrators to cause a denial of service (crash) or possibly gain privileges via unspecified vectors that overwrite memory in the hypervisor reserved range. | ||||
| CVE-2017-2615 | 5 Citrix, Debian, Qemu and 2 more | 10 Xenserver, Debian Linux, Qemu and 7 more | 2023-02-12 | N/A |
| Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. | ||||
| CVE-2015-5307 | 5 Canonical, Debian, Linux and 2 more | 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more | 2023-02-12 | 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-2019-17349 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 5.5 Medium |
| An issue was discovered in Xen through 4.12.x allowing Arm domU attackers to cause a denial of service (infinite loop) involving a LoadExcl or StoreExcl operation. | ||||
| CVE-2019-17342 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 7.0 High |
| 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 by leveraging a race condition that arose when XENMEM_exchange was introduced. | ||||
| CVE-2019-17341 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 7.8 High |
| 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 by leveraging a page-writability race condition during addition of a passed-through PCI device. | ||||
| CVE-2019-17350 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 5.5 Medium |
| An issue was discovered in Xen through 4.12.x allowing Arm domU attackers to cause a denial of service (infinite loop) involving a compare-and-exchange operation. | ||||
| CVE-2019-17348 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 6.5 Medium |
| An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service because of an incompatibility between Process Context Identifiers (PCID) and shadow-pagetable switching. | ||||
| CVE-2019-17347 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 7.8 High |
| 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). | ||||
| CVE-2019-17346 | 2 Debian, Xen | 2 Debian Linux, Xen | 2023-02-03 | 8.8 High |
| 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 of an incompatibility between Process Context Identifiers (PCID) and TLB flushes. | ||||
| CVE-2022-21127 | 3 Debian, Intel, Xen | 5 Debian Linux, Sgx Dcap, Sgx Psw and 2 more | 2023-01-31 | 5.5 Medium |
| Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||
| CVE-2022-23960 | 3 Arm, Debian, Xen | 42 Cortex-a57, Cortex-a57 Firmware, Cortex-a65 and 39 more | 2023-01-20 | 5.6 Medium |
| Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation, aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive information. | ||||
