CVE-2026-5358 (GCVE-0-2026-5358)

Vulnerability from cvelistv5 – Published: 2026-04-20 20:37 – Updated: 2026-04-22 13:04
VLAI

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.
