Collision attack against long Key Ids

[Nombre y Apellidos]

Hello

I'm a GPG user for a while, but I don't have any technical knowledge of
cryptography, only basic understanding of the subject. I mention this to
try and excuse my lack of knowledge.

I see a blog post about collisions in key Id's in this blog:
https://soatok.blog/2026/01/07/practical-collision-attack-against-long-key-ids-in-pgp/

According to the article itself, it can lead to cases of usurpation of
signed data, such as software packages.

Is it really a weakness in PGP/GNUPG?

Best regards and thanks in advanced
