CVE-2022-21125 5 Debian, Fedoraproject, Intel and 2 more 7 Debian Linux, Fedora, Sgx Dcap and 4 more 2025-05-05 2.1 LOW 5.5 MEDIUM
Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2022-21123 5 Debian, Fedoraproject, Intel and 2 more 7 Debian Linux, Fedora, Sgx Dcap and 4 more 2025-05-05 2.1 LOW 5.5 MEDIUM
Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
CVE-2022-42326 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2025-05-05 N/A 5.5 MEDIUM
Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] In case a node has been created in a transaction and it is later deleted in the same transaction, the transaction will be terminated with an error. As this error is encountered only when handling the deleted node at transaction finalization, the transaction will have been performed partially and without updating the accounting information. This will enable a malicious guest to create arbitrary number of nodes.
CVE-2015-8104 5 Canonical, Debian, Linux and 2 more 6 Ubuntu Linux, Debian Linux, Linux Kernel and 3 more 2025-04-23 4.7 MEDIUM 10.0 CRITICAL
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 #DB (aka Debug) exceptions, related to svm.c.
CVE-2017-10915 1 Xen 1 Xen 2025-04-20 6.8 MEDIUM 9.0 CRITICAL
The shadow-paging feature in Xen through 4.8.x mismanages page references and consequently introduces a race condition, which allows guest OS users to obtain Xen privileges, aka XSA-219.
CVE-2017-10923 1 Xen 1 Xen 2025-04-20 5.0 MEDIUM 6.5 MEDIUM
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-2017-14317 1 Xen 1 Xen 2025-04-20 4.7 MEDIUM 5.6 MEDIUM
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-2016-9817 1 Xen 1 Xen 2025-04-20 4.9 MEDIUM 6.5 MEDIUM
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving a (1) data or (2) prefetch abort with the ESR_EL2.EA bit set.
CVE-2016-9377 1 Xen 1 Xen 2025-04-20 2.1 LOW 5.5 MEDIUM
Xen 4.5.x through 4.7.x on AMD systems without the NRip feature, when emulating instructions that generate software interrupts, allows local HVM guest OS users to cause a denial of service (guest crash) by leveraging IDT entry miscalculation.
CVE-2016-9380 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 4.6 MEDIUM 7.5 HIGH
The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file.
CVE-2017-15592 1 Xen 1 Xen 2025-04-20 7.2 HIGH 8.8 HIGH
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-2016-9385 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 4.9 MEDIUM 6.0 MEDIUM
The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks.
CVE-2016-9379 2 Citrix, Xen 2 Xenserver, Xen 2025-04-20 4.6 MEDIUM 7.9 HIGH
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-2017-8903 1 Xen 1 Xen 2025-04-20 7.2 HIGH 8.8 HIGH
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-2017-8904 1 Xen 1 Xen 2025-04-20 6.8 MEDIUM 8.8 HIGH
Xen through 4.8.x mishandles the "contains segment descriptors" property during GNTTABOP_transfer (aka guest transfer) operations, which might allow PV guest OS users to execute arbitrary code on the host OS, aka XSA-214.
CVE-2017-15597 1 Xen 1 Xen 2025-04-20 9.0 HIGH 9.1 CRITICAL
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-2016-9818 1 Xen 1 Xen 2025-04-20 4.9 MEDIUM 6.5 MEDIUM
Xen through 4.7.x allows local ARM guest OS users to cause a denial of service (host crash) via vectors involving an asynchronous abort while at HYP.
CVE-2017-15588 1 Xen 1 Xen 2025-04-20 6.9 MEDIUM 7.8 HIGH
An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to execute arbitrary code on the host OS because of a race condition that can cause a stale TLB entry.
CVE-2016-9932 1 Xen 1 Xen 2025-04-20 2.1 LOW 3.3 LOW
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-2017-15594 1 Xen 1 Xen 2025-04-20 4.6 MEDIUM 8.8 HIGH
An issue was discovered in Xen through 4.9.x allowing x86 SVM PV guest OS users to cause a denial of service (hypervisor crash) or gain privileges because IDT settings are mishandled during CPU hotplugging.
