CVE-2026-37458: n/a
CVE-2026-37458 is a vulnerability in the MP_REACH_NLRI component of FRRouting versions stable/10.0 through stable/10.6. It involves missing input validation that allows authenticated attackers to cause a Denial of Service (DoS) by sending a crafted UPDATE message. The vulnerability has a CVSS score of 6.5, indicating a medium severity level. There is no confirmed patch or official remediation available at this time, and no known exploits in the wild have been reported.
AI Analysis
Technical Summary
This vulnerability arises from insufficient input validation in the MP_REACH_NLRI component of FRRouting (FRR) versions stable/10.0 to stable/10.6. Authenticated attackers can exploit this flaw by supplying a specially crafted BGP UPDATE message, which triggers a Denial of Service condition. The issue is tracked as CVE-2026-37458 and is categorized under CWE-20 (Improper Input Validation). The CVSS v3.1 base score is 6.5, reflecting a network attack vector with low attack complexity, requiring privileges, no user interaction, and resulting in high impact on availability only. No patch or official fix has been documented in the provided data.
Potential Impact
Successful exploitation results in a Denial of Service condition, impacting the availability of the FRRouting service. There is no impact on confidentiality or integrity according to the CVSS vector. The attack requires authenticated access and can be executed remotely over the network.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit authenticated access to the FRRouting service to trusted users only and monitor for unusual UPDATE message activity. Avoid deploying vulnerable versions in exposed environments where possible.
