Remediation/Fixes
IBM strongly recommends addressing the vulnerability now by visiting https://tape.ibmrcl.enterpriseappointments.com/v2/ or contacting IBM Service at 1-800-IBM-SERV to arrange an upgrade to the latest microcode version followed by the installation of VTD_EXEC.269 as needed. Minimum microcode versions are shown below:
| Machine Type | Model | Release | Fix |
| 3957 | VEC | R5.0 | Upgrade to 8.50.2.6 + VTD_EXEC.269 |
| R5.1 | Upgrade to 8.51.2.12 + VTD_EXEC.269 | ||
| R5.2 Phase 1 | Upgrade to 8.52.102.13 + VTD_EXEC.269 | ||
| R5.2 Phase 2 | Upgrade to 8.52.200.111 + VTD_EXEC.269 | ||
| VED | R5.0 | Upgrade to 8.50.2.6 + VTD_EXEC.269 | |
| R5.1 | Upgrade to 8.51.2.12 + VTD_EXEC.269 | ||
| R5.2 Phase 1 | Upgrade to 8.52.102.13 + VTD_EXEC.269 | ||
| R5.2 Phase 2 | Upgrade to 8.52.200.111 + VTD_EXEC.269 | ||
| R5.3 | Upgrade to 8.53.0.63 |
The minimum VTD_EXEC version is shown below:
| VTD_EXEC Package | Version |
| VTD_EXEC.269 | v2.00 |
Note: As of v2.00, VTD_EXEC.269 may be installed concurrently with online operations except on systems where the Cloud Storage Tier has been enabled with FC 5278, which will still require an outage.
Workarounds and Mitigations
Although IBM recommends that you upgrade to the fixes identified above, you can mitigate, but not eliminate the risk of these vulnerabilities by restricting physical and network access to the TS7700 to authorized users and IBM Service Personnel only.
