Short description: Security vulnerability on CPUs that use speculative execution

SpoilerCVE identifier(s)| CVE-2019-0162

|

Date discovered| November 2018; 7 years ago (2018-11)
Discoverer|  Worcester Polytechnic Institute
University of Lübeck
Affected hardware| Modern Intel microprocessors

Spoiler is a security vulnerability on modern computer central processing units that use speculative execution. It exploits side-effects of speculative execution to improve the efficiency of Rowhammer and other related memory and cache attacks. According to reports, all modern Intel Core CPUs are vulnerable to the attack as of 2019[update].[1][2] AMD has stated that its processors are not vulnerable.[3][4]

Spoiler was issued a Common Vulnerabilities and Exposures ID of CVE-2019-0162.
