CVE-2026-19667 is a numeric truncation error vulnerability in ISC BIND 9's named service. An attacker-controlled authoritative DNS server can craft a negative response exactly 65536 bytes in size, causing named to create a negative cache entry of 0 bytes. Subsequent reads of this entry cause named to abort, resulting in a denial of service. This affects multiple BIND 9 versions including 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and their respective S1 variants.
