The paper,

Passive SSH Key Compromise via Lattices
Keegan Ryan, Kaiwen He, George Arnold Sullivan, and Nadia Heninger
https://eprint.iacr.org/2023/1711.pdf

details an attack that allows a passive observer to potentially compromise RSA host keys. They also include details on internet-wide scans to measure the prevalence of vulnerable signatures in the wild.

I'm not aware if there is a CVE for this yet. The only other reference I have seen to it is this commit
