No official patch or remediation guidance is currently available, and no known exploits have been reported in the wild. The vulnerability is related to CWE-125 (Out-of-bounds Read).
AI Analysis
Technical Summary
An out-of-bounds read vulnerability exists in the ParseIP6Extended function within the bgp.go file of gobgp version 4.3.0. This vulnerability allows an unauthenticated attacker to cause a Denial of Service by sending a specially crafted BGP UPDATE message. The CVSS v3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and impact limited to availability. No patch or official remediation level has been disclosed as of the publication date.
Potential Impact
Successful exploitation results in a Denial of Service, disrupting the availability of the gobgp service. There is no impact on confidentiality or integrity. The vulnerability can be triggered remotely without authentication, making it a significant risk for affected deployments.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider implementing network-level protections such as filtering or rate limiting BGP UPDATE messages from untrusted sources to reduce exposure.
