Go 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.

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
