The remaining CVEs disclosed in VU#257161 have been assessed and found to be not applicable to Intel Products.

Note: Firmware versions of Intel® ME 3.x thru 10.x, Intel® TXE 1.x thru 2.x and Intel® Server Platform Services 1.x thru 2.X are no longer supported, thus were not assessed for the vulnerabilities/CVEs listed in this Technical Advisory. There is no new release planned for these versions.

Recommendations:

Intel recommends that users of Intel® CSME, Intel® SPS, Intel® TXE, Intel® AMT, Intel® ISM and Intel® DAL update to the latest versions provided by the system manufacturer that address these issues.
