| CVE-2026-13321 | Hig | 8.6 | < 32:9.16.23-0.22.el8_10.12 | 32:9.16.23-0.22.el8_10.12 | Jul 22, 2026 | The BIND resolver accepts validly-signed NSEC records where the "Next Domain Name" field points outside the signer's zone. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 throug | |

This causes `named` to produce a wildcard name for a zone that is shorter than the attacker's zone, which can result in cac | |

The attacker needs to be able to send queries faster than the resolver can perform validation. The increased memory usage can be orders of magni | |
| CVE-2026-11331 | Hig | 7.5 | < 32:9.16.23-0.22.el8_10.12 | 32:9.16.23-0.22.el8_10.12 | Jul 22, 2026 | An attacker who knows (or guesses) that a resolver uses RPZ with wildcard CNAME policies can craft query names long enough to trigger a NAMETOOLONG error condition during RPZ processing. This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an | |
| CVE-2026-10723 | Med | 6.8 | < 32:9.16.23-0.22.el8_10.12 | 32:9.16.23-0.22.el8_10.12 | Jul 22, 2026 | BIND may accept incorrect child-zone NSEC3 records as valid, which could allow an attacker to forge authenticated NXDOMAIN responses. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.11.3-S1 through 9.18.50-S1, and 9.20. | |

Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries (see: | |

This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11 | |

This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through 9.11.37 | |
