"On August 15, 2018, security vulnerabilities codenamed Foreshadow/L1TF (CVE-2018-3620, CVE-2018-3646 and CVE-2018-3615) were announced. Two of the vulnerabilities (CVE-2018-3620 and CVE-2018-3646) could potentially impact Power Systems. The Firmware and OS patches released by IBM in February and March 2018 to address the original Meltdown vulnerability (CVE-2017-5754) also address the L1TF/Foreshadow vulnerability, except for Power 9 Systems running with KVM Hypervisor. OS patch for Power 9 KVM Systems will be made available soon. The Firmware and OS patches for all other Power Systems are available in this blog below. The third L1TF/Foreshadow vulnerability (CVE-2018-3615) relates to SGX implementation and does not impact the Power Systems."
