CVE-2021-27795

Brocade Fabric OS (FOS) hardware 
platforms running any version of Brocade Fabric OS software, which 
supports the license string format; contain cryptographic 
issues that could allow for the installation of forged or fraudulent 
license keys. This would allow attackers or a malicious party to forge a
 counterfeit license key that the Brocade Fabric OS platform would 
authenticate and activate as if it were a legitimate license key.
