CVE-2019-6486 is a high-severity vulnerability affecting Go versions before 1.10.8 and 1.11.5, specifically concerning its handling of P-521 and P-384 elliptic curves. This flaw allows remote attackers to trigger a denial of service through high CPU consumption or potentially facilitate ECDH private key recovery attacks. With a CVSS score of 8.2 (High), the vulnerability is network-exploitable with low attack complexity, posing a significant risk of service disruption and potential information disclosure. Despite its severity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.

golang: crypto/elliptic implementations of P-521 and P-384 elliptic curves allow for denial of service
Jan 24, 2019Go before 1.10.8 and 1.11.x before 1.11.5 mishandles P-521 and P-384 elliptic curves, which allows attackers to cause a denial of service (CPU consumption) or possibly conduct ECDH private key recovery attacks.
