Please refer to MOS Document 888828.1 for important considerations before upgrading to the latest Exadata System Software release. As stated, before updating database servers (non-OVM and OVM domU) to Exadata 18.1.5 or higher, ensure ACFS drivers that support the most efficient CVE-2017-5715 (Spectre Variant 2) mitigation are installed. These updated ACFS drivers, required for Exadata versions >= 18.104.22.168.0 and >= 22.214.171.124.7, are included in the July 2018 quarterly database releases. Quarterly database releases from April 2018 and earlier still require a separate ACFS patch. See MOS Document 2356385.1 for details.
MOS Document 2357480.1 discusses the performance impact of mitigation measures against CVE-2017-5754, CVE-2017-5753, and CVE-2017-5715 on Oracle Database, Oracle Exadata and Oracle Zero Data Loss Recovery Appliance.
Database servers that have been customized by installing third-party kernel drivers must contact the third-party vendor to obtain updated third-party drivers. See MOS Document 2356385.1 for details. For further information, see:
