Workarounds & Mitigations

CVE ID Workaround and Mitigation
CVE-2024-20397

For Cisco MDS and Nexus standalone platforms, if the device was not previously upgraded by using the install all CLI command, the BIOS might not have been upgraded. Even if customers are running a fixed Cisco NX-OS Software release, they are advised to check the BIOS version and use the install all command to complete the BIOS upgrade, if applicable.

So even if the device is running the fixed release we recommend checking the actual BIOS version to be sure.
