{"id":"ALPINE-CVE-2026-79610","details":"XSA-501 was about issues with v1 -\u003e v2 and v2 -\u003e v1 changes racing certain\nother grant table operations.  Sadly a v2 -\u003e v1 -\u003e v2 change has yet\nanother effect which wasn't accounted for: During the first change, status\npages would be freed.  During the second change they would be allocated\nagain.  Hence across the full pair of change the addresses of the status\npages may change, rendering stale previously calculated pointers into the\nstatus array.","modified":"2026-10-14T09:30:02.448144739Z","published":"2026-10-13T16:17:23.247Z","upstream":["CVE-2026-79610"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-79610"}],"affected":[{"package":{"name":"xen","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/xen?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.19.6-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-79610.json"}},{"package":{"name":"xen","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/xen?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.4-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-79610.json"}},{"package":{"name":"xen","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xen?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.20.4-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-79610.json"}},{"package":{"name":"xen","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xen?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.21.2-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-79610.json"}}],"schema_version":"1.9.0"}
