CVE-2026-37459: n/a
An integer underflow in FRRouting (FRR) stable/10.0 to stable/10.6 allows attackers to cause a Denial of Service (DoS) via supplying a crafted BGP UPDATE message.
AI Analysis
Technical Summary
This vulnerability involves an integer underflow in FRRouting (FRR) stable versions 10.0 to 10.6. An attacker can exploit this by supplying a crafted BGP UPDATE message, which causes the affected software to crash or become unavailable, leading to a Denial of Service. The vulnerability is documented as CVE-2026-37459 but lacks a CVSS score and detailed remediation information.
Potential Impact
Successful exploitation causes a Denial of Service in FRRouting, disrupting routing operations that rely on BGP. No evidence of code execution or data compromise is indicated. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider limiting exposure to untrusted BGP peers and monitoring for anomalous BGP UPDATE messages that could trigger the vulnerability.
