CVE-2020-24512: Infoleak
First published: Thu May 20 2021(Updated: )
Certain optimizations on some Intel processors target “trivial data value” cache-lines, such as all-zero value cache-lines. Such optimizations may lead to changes in cache-allocation or write-back behavior for such cache-lines. It may be possible for a local attacker to distinguish some cases of trivial-data-cache-lines from non-trivial-data cache-lines by inferring cache state using cache timing methods.
