| CVE-2022-42318 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2025-05-05 | 6.5 Medium |
| Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction | ||||

| Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||

| 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 | 6 Debian, Fedoraproject, Intel and 3 more | 14 Debian Linux, Fedora, Sgx Dcap and 11 more | 2025-05-05 | 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 | 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 | 6 Canonical, Debian, Linux and 3 more | 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more | 2025-04-23 | 10 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-2017-10913 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1. | ||||
| CVE-2017-10919 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| Xen through 4.8.x mishandles virtual interrupt injection, which allows guest OS users to cause a denial of service (hypervisor crash), aka XSA-223. | ||||
| CVE-2017-10914 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x has a race condition leading to a double free, which allows guest OS users to cause a denial of service (memory consumption), or possibly obtain sensitive information or gain privileges, aka XSA-218 bug 2. | ||||
| CVE-2017-14316 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array. | ||||
| CVE-2017-10915 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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-2017-10921 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x does not ensure sufficient type counts for a GNTMAP_device_map and GNTMAP_host_map mapping, which allows guest OS users to cause a denial of service (count mismanagement and memory corruption) or obtain privileged host OS access, aka XSA-224 bug 2. | ||||
| CVE-2017-15590 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service (hypervisor crash) or possibly gain privileges because MSI mapping was mishandled. | ||||
| CVE-2017-15596 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen 4.4.x through 4.9.x allowing ARM guest OS users to cause a denial of service (prevent physical CPU usage) because of lock mishandling upon detection of an add-to-physmap error. | ||||
| CVE-2017-15593 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| An issue was discovered in Xen through 4.9.x allowing x86 PV guest OS users to cause a denial of service (memory leak) because reference counts are mishandled. | ||||
| CVE-2017-15594 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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. | ||||
| 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-2017-10922 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| The grant-table feature in Xen through 4.8.x mishandles MMIO region grant references, which allows guest OS users to cause a denial of service (loss of grant trackability), aka XSA-224 bug 3. | ||||
| CVE-2017-15588 | 1 Xen | 1 Xen | 2025-04-20 | N/A |
| 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. | ||||
