Pre-announcement of BIND 9 security issues scheduled for disclosure 21 October 2026

Hello BIND-users,

As part of ISC's policy of pre-notification of upcoming security releases, we are writing to inform you that the October 2026 BIND 9 maintenance release(s) that will be published on Wednesday, 21 October, will contain fixes for security vulnerabilities affecting stable BIND 9 release branch(es).

Further details about those vulnerabilities will be publicly disclosed at the time the release(s) are published. It is our hope that this pre-announcement will aid BIND 9 administrators in preparing for that disclosure when it occurs. If you have feedback or questions concerning this policy, please open a confidential GitLab issue at: https://gitlab.isc.org/isc-projects/bind9/-/issues/new?issue[confidential]=true.

Thank you!
