{"id":"AZL-113732","summary":"CVE-2026-116328 affecting package postgresql 16.15-1","details":"Integer wraparound in PostgreSQL generation memory contexts allows a database user to execute arbitrary code as the operating system user running the database, via freeing an allocation larger than 1 GB and causing its block to be reused for smaller chunks whose back-pointer offset cannot represent that position.  Within major versions 16-18, minor versions before PostgreSQL 18.7, 17.12, and 16.16 are affected.  Versions before PostgreSQL 16 are unaffected.","modified":"2026-11-13T14:17:11.470739615Z","published":"2026-11-12T15:17:41Z","upstream":["CVE-2026-116328"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-116328"}],"affected":[{"package":{"name":"postgresql","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/postgresql"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"16.15-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113732.json"}}],"schema_version":"1.9.2"}
