Go is not vulnerable in the same way software using webpki is, because it generally uses the system trust store. However, this change is about golang proactively blocking the certs, so that even if your OS doesn't update, it still won't trust them.
curl: (60) SSL certificate OpenSSL verify result: unable to get local issuer certificate (20)
More details here: https://curl.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the webpage mentioned above.
Great. The technology has progressed enough to kill the existing technologies. It's like the fish in a pool creating a shark that eats away all the fish while the fish proudly announce that their great creation (shark) as the frontier progress for their fish race.
In other words, that software bundled the compromised certs into the binary, so upgrading it is the only way to remove them.
This is about Go proactively blocking intermediates. Which shouldn't strictly be necessary as long as your OS has removed or distrusted the CAs (on my laptop, macOS has done that, although it seems like it did so in a way not all tools have access to; for example, rustls-platform-verifier respects it, but rustls-webpki still loads the bad CAs from the system trust store).

The problem is Golang has it's own trust store. So you don't benefit from OS patching.
If you think "that's weird to see such a small number in key generation" than you're one step ahead of whoever generated that key.
Unfortunately, unlike with RSA, small primes are not apparent in elliptic cryptography.

The very urgent uv/certifi/etc releases (and yet-to-be-done bun release) are about removing the compromised CAs as described here:
