CVE-2021-3714 (GCVE-0-2021-3714)

Vulnerability from cvelistv5 – Published: 2022-08-23 15:51 – Updated: 2024-08-03 17:01
VLAI?
Summary
A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a networked service to determine if the page has been merged.
Severity ?
No CVSS data available.
