Prior to v2.6.3, an attacker can send NodeInfo with a empty publicKey first, then overwrite it with a new key. First sending a empty key bypasses 'if (p.public_key.size > 0) {', clearing the existing publicKey (and resetting the size to 0) for a known node. Then a new key bypasses 'if (info->user.public_key.size > 0) {', and this malicious key is stored in NodeDB. This vulnerability is fixed in 2.6.3.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2025-55293","url":"https://www.suse.com/security/cve/CVE-2025-55293"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1248251 for CVE-2025-55293","url":"https://bugzilla.suse.com/1248251"}],"title":"SUSE CVE CVE-2025-55293","tracking":{"current_release_date":"2025-08-19T23:21:47Z","generator":{"date":"2025-08-19T23:21:47Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-55293","initial_release_date":"2025-08-19T23:21:47Z","revision_history":[{"date":"2025-08-19T23:21:47Z","number":"2","summary":"Current version"}],"status":"interim","version":"2"}}}
