| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-03-21 | CVE-2022-42334 | Allocation of Resources Without Limits or Throttling vulnerability in multiple products x86/HVM pinned cache attributes mis-handling T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. | 6.5 |
| 2022-11-01 | CVE-2022-42310 | Incomplete Cleanup vulnerability in multiple products Xenstore: Guests can create orphaned Xenstore nodes By creating multiple nodes inside a transaction resulting in an error, a malicious guest can create orphaned nodes in the Xenstore data base, as the cleanup after the error will not remove all nodes already created. | 5.5 |
| 2022-11-01 | CVE-2022-42319 | Memory Leak vulnerability in multiple products Xenstore: Guests can cause Xenstore to not free temporary memory When working on a request of a guest, xenstored might need to allocate quite large amounts of memory temporarily. | 6.5 |
| 2022-11-01 | CVE-2022-42325 | Memory Leak vulnerability in multiple products 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. | 5.5 |
| 2022-11-01 | CVE-2022-42326 | Memory Leak vulnerability in multiple products 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. | 5.5 |
| 2022-10-11 | CVE-2022-33748 | Improper Handling of Exceptional Conditions vulnerability in multiple products lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. | 5.6 |
| 2022-04-05 | CVE-2022-26356 | Improper Locking vulnerability in multiple products Racy interactions between dirty vram tracking and paging log dirty hypercalls Activation of log dirty mode done by XEN_DMOP_track_dirty_vram (was named HVMOP_track_dirty_vram before Xen 4.9) is racy with ongoing log dirty hypercalls. | 5.6 |
| 2022-04-05 | CVE-2022-26357 | Race Condition vulnerability in multiple products race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. | 7.0 |
| 2022-01-25 | CVE-2022-23034 | Integer Underflow (Wrap or Wraparound) vulnerability in multiple products A PV guest could DoS Xen while unmapping a grant To address XSA-380, reference counting was introduced for grant mappings for the case where a PV guest would have the IOMMU enabled. | 5.5 |
| 2022-01-25 | CVE-2022-23035 | Incomplete Cleanup vulnerability in multiple products Insufficient cleanup of passed-through device IRQs The management of IRQs associated with physical devices exposed to x86 HVM guests involves an iterative operation in particular when cleaning up after the guest's use of the device. | 4.6 |
