Pre-announcement of BIND 9 security issue scheduled for disclosure 21 January 2026

[Victoria Risk]

BIND-users,

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

Further details about this vulnerability 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 (preferred) or send an email to bind-security at isc.org.
