["Het Patel -X (hetpat - E INFOCHIPS PRIVATE LIMITED at Cisco)" <hetpat@cisco.com>]

From: Peter Marko <peter.marko@siemens.com>

As of now, update of CVE DB from FKIE source (which is the defailt)
fails with following error:

File: '<build>/poky/meta/recipes-core/meta/cve-update-db-native.bb', lineno: 393, function: update_db_fkie
     0389:                [cveId, cveDesc, cvssv2, cvssv3, cvssv4, date, accessVector, vectorString]).close()
     0390:
     0391:        for config in elt['configurations']:
     0392:            # This is suboptimal as it doesn't handle AND/OR and negate, but is better than nothing
 *** 0393:            for node in config["nodes"]:
     0394:                parse_node_and_insert(conn, node, cveId, False)
     0395:
     0396:def update_db(d, conn, jsondata):
     0397:    if (d.getVar("NVD_DB_VERSION") == "FKIE"):
Exception: KeyError: 'nodes'

Entry for new CVE-2025-32915 is broken.
