CVE-2026-101339 is fixed in nsd on 1 platform by DEBIAN-CVE-2026-101339 (version 4.15.3-1), released October 18, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A HIP resource record that fills the RDATA near or at is limit, and has another dname RDATA field (a HIP Rendezvous server) can overwrite the stack with up to 191 bytes of attacker controlled data. Zone files which are written out by NSD itself, such as for zones for which the NSD instance is secondary, will not be formatted like this. The zone file must be fed to NSD directly, (but it could come, for example, from an operator controlled provisioning system).
