{"id":"AZL-103353","summary":"CVE-2026-75029 affecting package bind 9.20.26-1","details":"In a query response, an attacker may send `named` multiple copies of a record that should only exist once (such as an SOA record). If the RDATA is the same on all the copies, the record is appended to the in-memory RDATA set, which can cause increased memory usage of the negative cache and possibly lead to other memory attack vectors.\nThis issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.","modified":"2026-09-23T05:36:13Z","published":"2026-09-16T15:17:43Z","upstream":["CVE-2026-75029"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75029"}],"affected":[{"package":{"name":"bind","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/bind"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"9.20.26-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103353.json"}}],"schema_version":"1.9.0"}
