| CVE-2017-10923 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x does not validate a vCPU array index upon the sending of an SGI, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-225. | ||||
| CVE-2016-9386 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | ||||
| 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-2017-15592 | 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 cause a denial of service (hypervisor crash) or possibly gain privileges because self-linear shadow mappings are mishandled for translated guests. | ||||
| 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-2017-17564 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing guest OS users to cause a denial of service (host OS crash) or gain host OS privileges by leveraging incorrect error handling for reference counting in shadow mode. | ||||
| CVE-2015-7504 | 4 Debian, Qemu, Redhat and 1 more | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-20 | 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. | ||||
| CVE-2016-9383 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. | ||||
| CVE-2017-14317 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| A domain cleanup issue was discovered in the C xenstore daemon (aka cxenstored) in Xen through 4.9.x. When shutting down a VM with a stubdomain, a race in cxenstored may cause a double-free. The xenstored daemon may crash, resulting in a DoS of any parts of the system relying on it (including domain creation / destruction, ballooning, device changes, etc.). | ||||
| 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-2016-9379 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | ||||
| CVE-2017-12136 | 3 Citrix, Debian, Xen | 3 Xenserver, Debian Linux, Xen | 2025-04-20 | N/A |
| Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. | ||||
| CVE-2017-15597 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. Privilege escalation and information leaks cannot be ruled out. | ||||
| CVE-2016-10024 | 2 Citrix, Xen | 2 Xenserver, Xen | 2025-04-20 | N/A |
| Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations. | ||||
| CVE-2016-9932 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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. | ||||
| CVE-2017-14431 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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. | ||||
| 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-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-2014-7155 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Opensuse and 1 more | 2025-04-12 | N/A |
| The x86_emulate function in arch/x86/x86_emulate/x86_emulate.c in Xen 4.4.x and earlier does not properly check supervisor mode permissions, which allows local HVM users to cause a denial of service (guest crash) or gain guest kernel mode privileges via vectors involving an (1) HLT, (2) LGDT, (3) LIDT, or (4) LMSW instruction. | ||||
| 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. | ||||
