Vendor

Canonical Ubuntu

Versions Affected
  • Canonical Ubuntu 14.04
  • Canonical Ubuntu 16.04
Description

Moritz Lipp, Michael Schwarz, Andreas Kogler, David Oswald, Catherine Easdon, Claudio Canella, and Daniel Gruss discovered that the Intel Running Average Power Limit (RAPL) feature of some Intel processors allowed a side- channel attack based on power consumption measurements. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8695)

Ezra Caltum, Joseph Nuzman, Nir Shildan and Ofir Joseff discovered that some Intel(R) Processors did not properly remove sensitive information before storage or transfer in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8696)

Ezra Caltum, Joseph Nuzman, Nir Shildan and Ofir Joseff discovered that some Intel(R) Processors did not properly isolate shared resources in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2020-8698)
