A vulnerability was found in BIND 9 resolvers, where processing malformed DNSKEY records from a specially crafted zone can lead to resource exhaustion, primarily causing excessive CPU utilization. This issue enables a remote, unauthenticated attacker to degrade resolver performance and potentially cause a denial of service (DoS) for legitimate DNS clients.

There were reported regressions shortly after release of 9.18.41 and 9.20.15 version. Our builds should have them fixed. It failed on RHEL9 or RHEL10, where SHA-1 based signatures are considered insecure. When the domain is signed with both unsupported algorithm (such as 5 or 7) and supported algorithm at the same time, it resulted in SERVFAIL after CVE fixes applied. https://gitlab.isc.org/isc-projects/bind9/-/issues/5622 https://gitlab.isc.org/isc-projects/bind9/-/merge_requests/11202 This issue has been addressed in the following products: Red Hat Enterprise Linux 10 Via RHSA-2025:19912 https://access.redhat.com/errata/RHSA-2025:19912 This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2025:19950 https://access.redhat.com/errata/RHSA-2025:19950 This issue has been addressed in the following products: Red Hat Enterprise Linux 10 Via RHSA-2025:21034 https://access.redhat.com/errata/RHSA-2025:21034 This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2025:21111 https://access.redhat.com/errata/RHSA-2025:21111 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.20 Via RHSA-2026:0420 https://access.redhat.com/errata/RHSA-2026:0420 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.12 Via RHSA-2026:0316 https://access.redhat.com/errata/RHSA-2026:0316 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.16 Via RHSA-2026:0326 https://access.redhat.com/errata/RHSA-2026:0326 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.18 Via RHSA-2026:0332 https://access.redhat.com/errata/RHSA-2026:0332 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.17 Via RHSA-2026:0702 https://access.redhat.com/errata/RHSA-2026:0702 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.13 Via RHSA-2026:0677 https://access.redhat.com/errata/RHSA-2026:0677 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.19 Via RHSA-2026:0674 https://access.redhat.com/errata/RHSA-2026:0674 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.14 Via RHSA-2026:0996 https://access.redhat.com/errata/RHSA-2026:0996 This issue has been addressed in the following products: Red Hat OpenShift Container Platform 4.15 Via RHSA-2026:1541 https://access.redhat.com/errata/RHSA-2026:1541 This issue has been addressed in the following products: Red Hat Enterprise Linux 9 Via RHSA-2026:18786 https://access.redhat.com/errata/RHSA-2026:18786 |
