How to fix?

Upgrade Minimos:latest go-discover to version 0_git20260602-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream go-discover package and not the go-discover package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
