|---|---|---|---|
| 2023-05-17 | CVE-2022-42336 | Unspecified vulnerability in XEN 4.17 Mishandling of guest SSBD selection on AMD hardware The current logic to set SSBD on AMD Family 17h and Hygon Family 18h processors requires that the setting of SSBD is coordinated at a core level, as the setting is shared between threads. | 3.3 |
| 2023-04-25 | CVE-2022-42335 | NULL Pointer Dereference vulnerability in multiple products x86 shadow paging arbitrary pointer dereference In environments where host assisted address translation is necessary but Hardware Assisted Paging (HAP) is unavailable, Xen will run guests in so called shadow mode. | 7.8 |
| 2023-03-21 | CVE-2022-42331 | x86: speculative vulnerability in 32bit SYSCALL path Due to an oversight in the very original Spectre/Meltdown security work (XSA-254), one entrypath performs its speculation-safety actions too late. | 5.5 |
| 2023-03-21 | CVE-2022-42332 | Use After Free vulnerability in multiple products x86 shadow plus log-dirty mode use-after-free In environments where host assisted address translation is necessary but Hardware Assisted Paging (HAP) is unavailable, Xen will run guests in so called shadow mode. | 7.8 |
| 2023-03-21 | CVE-2022-42333 | 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. | 8.6 |
| 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 |
| 2023-01-26 | CVE-2022-42330 | Unspecified vulnerability in XEN 4.17.0 Guests can cause Xenstore crash via soft reset When a guest issues a "Soft Reset" (e.g. | 7.5 |
| 2022-11-09 | CVE-2022-23824 | IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. | 5.5 |
| 2022-11-01 | CVE-2022-42309 | Release of Invalid Pointer or Reference vulnerability in multiple products Xenstore: Guests can crash xenstored Due to a bug in the fix of XSA-115 a malicious guest can cause xenstored to use a wrong pointer during node creation in an error path, resulting in a crash of xenstored or a memory corruption in xenstored causing further damage. | 8.8 |
| 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 |
