A major result in post-quantum cryptography. A key security assumption behind Classic McEliece, a public-key encryption system considered to resist quantum computers, has been undermined. Researchers found a provable quasipolynomial-time method for detecting the hidden mathematical structure in its public keys. The attack is still astronomically expensive and cannot yet decrypt messages, but this is a serious weakening of one of the oldest post-quantum cryptosystems. McEliece is not broken practically today, but an important assumption underlying its theoretical security has been broken. For the Classic McEliece parameter sets, the estimated cost of the best known structural distinguisher drops from roughly 2^298-2^691 operations to about 2^114-2^124. That is huge.

Looks like they rotated all signings keys a day earlier:

In October 2025, F5 rotated its signing certificates and keys used to cryptographically sign F5-produced digital objects.

As a result:

    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later are signed with new certificates and keys
    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later contain new public keys used to verify certain F5-produced objects released in October 2025 and later
    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later may not be able to verify certain F5-produced objects released prior to October 2025
    BIG-IP and BIG-IQ TMOS product versions released prior to October 2025 may not be able to verify certain F5-produced objects released in October 2025 and later
