{"id":"AZL-86822","summary":"CVE-2026-6473 affecting package postgresql for versions less than 16.14-1","details":"Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds.  This may execute arbitrary code as the operating system user running the database.  In applications that pass gigabyte-scale user inputs to the relevant database functions, the application input provider may achieve a segmentation fault.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.","modified":"2026-08-28T17:46:05.189418592Z","published":"2026-05-14T14:16:24Z","upstream":["CVE-2026-6473"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6473"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"16.14-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86822.json"}}],"schema_version":"1.9.0"}
