TITLE

Intel Processors Information disclosure vulnerability

Trust: 0.6

sources: CNNVD: CNNVD-202106-632

DESCRIPTION

Domain-bypass transient execution vulnerability in some Intel Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Intel Processors (Intel processors) are Intel Corporation's processors that interpret computer instructions and process data in computer software. An unauthorized attacker could exploit the vulnerability to obtain sensitive information of the affected components. 6 ELS) - i386, x86_64 3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: microcode_ctl security, bug fix and enhancement update Advisory ID: RHSA-2021:2305-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:2305 Issue date: 2021-06-08 CVE Names: CVE-2020-24489 CVE-2020-24511 CVE-2020-24512 CVE-2020-24513 ==================================================================== 1.
