Affected: Go toolchain cmd/cgo, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.2 Advanced Update Support, Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On, Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Telecommunications Update Service, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions and 23 more

A discrepancy between how Go and C/C++ comments were parsed allowed for code smuggling into the resulting cgo binary.

Affected: Go: filippo.io/edwards25519

`(*Point).MultiScalarMult` failed to initialize its receiver.

If the method was called on an initialized point that is not the identity point, MultiScalarMult produced an incorrect result.

If the method was called on an uninitialized point, the behavior was undefined. In particular, if the receiver was the zero value, MultiScalarMult returned an invalid point that compared Equal to every point.

*Note that MultiScalarMult is a rarely used advanced API. For example, if you only depend on `filippo.io/edwards25519` via `github.com/go-sql-driver/mysql`, **you are not affected**. If you were notified of this issue despite not being affected, consider switching to a vulnerability scanner that is more precise and respectful of your attention, like [govulncheck](https://go.dev/doc/tutorial/govulncheck).*
