This is, for instance, used when allocating guest memory to ensure any writes (such as the ones during scrubbing) have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the helpers can overflow and would then result to skip the cache cleaning/invalidation.

Since Xen itself needs to be mapped when PV guests run, Xen and shadowed PV guests run directly the respective shadow page tables. For 64-bit PV guests this means running on the shadow of the guest root page table. In the course of dealing with shortage of memory in the shadow pool associated with a domain, shadows of page tables may be torn down. This tearing down may include the shadow root page table that the CPU in question is presently running on. While a precaution exists to supposedly prevent the tearing down of the underlying live page table, the time window covered by that precaution isn't large enough.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2023-34322", "reference_id": "", "reference_type": "", "scores": [ { "value": "0.00058", "scoring_system": "epss", "scoring_elements": "0.18622", "published_at": "2026-06-05T12:55:00Z" } ], "url": "https://api.first.org/data/v1/epss?cve=CVE-2023-34322" }, { "reference_url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-34322", "reference_id": "", "reference_type": "", "scores": [], "url": "https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-34322" }, { "reference_url": "https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml", "reference_id": "", "reference_type": "", "scores": [ { "value": "7.5", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H" } ], "url": "https://ftp.suse.com/pub/projects/security/yaml/suse-cvss-scores.yaml" }, { "reference_url": "https://xenbits.xenproject.org/xsa/advisory-438.html", "reference_id": "advisory-438.html", "reference_type": "", "scores": [ { "value": "7.8", "scoring_system": "cvssv3.1", "scoring_elements": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H" }, { "value": "Track", "scoring_system": "ssvc", "scoring_elements": "SSVCv2/E:N/A:Y/T:P/P:M/B:A/M:M/D:T/2024-08-27T15:50:09Z/" } ], "url": "https://xenbits.xenproject.org/xsa/advisory-438.html" }, { "reference_url": "https://security.gentoo.org/glsa/202409-10", "reference_id": "GLSA-202409-10", "reference_type": "", "scores": [], "url": "https://security.gentoo.org/glsa/202409-10" }, { "reference_url": "https://xenbits.xen.org/xsa/advisory-438.html", "reference_id": "XSA-438", "reference_type": "", "scores": [], "url": "https://xenbits.xen.org/xsa/advisory-438.html" } ], "fixed_packages": [ { "url": "http://public2.vulnerablecode.io/api/packages/349505?format=api", "purl": "pkg:apk/alpine/xen@4.17.2-r1?arch=s390x&distroversion=v3.21&reponame=main", "is_vulnerable": false, "affected_by_vulnerabilities": [], "resource_url": "http://public2.vulnerablecode.io/packages/pkg:apk/alpine/xen@4.17.2-r1%3Farch=s390x&distroversion=v3.21&reponame=main" } ], "aliases": [ "CVE-2023-34322", "XSA-438" ], "risk_score": null, "exploitability": "0.5", "weighted_severity": "0.0", "resource_url": "http://public2.vulnerablecode.io/vulnerabilities/VCID-cgzn-pdre-1bec" } ], "risk_score": null, "resource_url": "http://public2.vulnerablecode.io/packages/pkg:apk/alpine/xen@4.17.2-r1%3Farch=s390x&distroversion=v3.21&reponame=main" }
