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.  Therefore there is no guarantee when all the writes will reach the memory.  This undefined behavior was meant to be addressed by XSA-437, but the approach was not sufficient.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2023-46837","reference_id":"","reference_type":"","scores":[{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23901","published_at":"2026-06-05T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23787","published_at":"2026-06-09T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23782","published_at":"2026-06-08T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23835","published_at":"2026-06-07T12:55:00Z"},{"value":"0.00081","scoring_system":"epss","scoring_elements":"0.23885","published_at":"2026-06-06T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2023-46837"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-46837","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-46837"},{"reference_url":"https://xenbits.xenproject.org/xsa/advisory-447.html","reference_id":"advisory-447.html","reference_type":"","scores":[{"value":"3.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-02-01T20:11:12Z/"}],"url":"https://xenbits.xenproject.org/xsa/advisory-447.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://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/JFVKWYQFRUU3CAS53THTUKXEOUDWI42G/","reference_id":"JFVKWYQFRUU3CAS53THTUKXEOUDWI42G","reference_type":"","scores":[{"value":"3.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-02-01T20:11:12Z/"}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/JFVKWYQFRUU3CAS53THTUKXEOUDWI42G/"},{"reference_url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XLL6SQ6IKFYXLYWITYZCRV5IBRK5G35R/","reference_id":"XLL6SQ6IKFYXLYWITYZCRV5IBRK5G35R","reference_type":"","scores":[{"value":"3.3","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2024-02-01T20:11:12Z/"}],"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XLL6SQ6IKFYXLYWITYZCRV5IBRK5G35R/"},{"reference_url":"https://xenbits.xen.org/xsa/advisory-447.html","reference_id":"XSA-447","reference_type":"","scores":[],"url":"https://xenbits.xen.org/xsa/advisory-447.html"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/398706?format=json","purl":"pkg:apk/alpine/xen@4.18.0-r2?arch=ppc64le&distroversion=v3.21&reponame=main","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/xen@4.18.0-r2%3Farch=ppc64le&distroversion=v3.21&reponame=main"}],"aliases":["CVE-2023-46837","XSA-447"],"risk_score":1.5,"exploitability":"0.5","weighted_severity":"3.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-f7v4-85sw-1keq"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:apk/alpine/xen@4.18.0-r2%3Farch=ppc64le&distroversion=v3.21&reponame=main"}
