The Debian security team deemed this advisory irrelevant for Debian:unstable.
NVD Description
Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Debian.
Rejected reason: REJECTED: CVE-2026-5358 is rejected for two reasons. Firstly it has been discovered that no NIS+ client or server was ever released for any Linux-based OS distributions and as such this makes the API provisional and unused. Secondly it has been discovered that the NIS+ cold start cache (/var/nis/NIS_COLD_START) cannot be bypassed and as such the API can only be called with a trusted server from the pre-populated cache. The use of a trusted server means no trust boundary is crossed and this is therefore considered a normal bug.
