once this PR is approved, I will provide the the other PR's due to the fact that the other PR's need the base files (arm64.s and arm64.go) |

what should be considered is the alignment of the poly array. The difference between unaligned and aligned loads and stores needs to be tested. |

Note: it's not necessary here, but you can reuse V0 or V4 as target register.

The issue is fixed by using complete addition formulas. ECDH and ECDSA signing relying on this curve are not affected. The bug was fixed in **[v1.6.3](https://github.com/cloudflare/circl/releases/tag/v1.6.3)**. #### Severity - CVSS Score: 2.9 / 10 (Low) - Vector String: `CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/E:P/S:N/AU:Y/U:Amber` #### References -
