{"id":"ALPINE-CVE-2026-6575","details":"Buffer over-read in PostgreSQL function pg_restore_attribute_stats() accepts array values of unmatched length, which causes query planning to read past end of one array.  This allows a table maintainer to infer memory values past that array end.  Within major version 18, minor versions before PostgreSQL 18.4 are affected.  Versions before PostgreSQL 18 are unaffected.","modified":"2026-09-14T16:18:08.256921810Z","published":"2026-05-14T14:16:25.693Z","upstream":["CVE-2026-6575"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-6575"}],"affected":[{"package":{"name":"postgresql18","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/postgresql18?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-6575.json"}},{"package":{"name":"postgresql18","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/postgresql18?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"18.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-6575.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
