The write operation is split into STA (STore Address) and STD (STore Data) sub-operations. These sub-operations allow the processor to hand-off address generation logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'. As a result, an unprivileged attacker could use this flaw to read private data resident within the CPU's processor store buffer."], "name": "CVE-2018-12126", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:5", "fix_state": "Will not fix", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 5"}, {"cpe": "cpe:/o:redhat:rhev_hypervisor:4", "fix_state": "Affected", "package_name": "ovirt-guest-agent", "product_name": "Red Hat Virtualization 4"}], "public_date": "2019-05-14T17:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2018-12126\nhttps://nvd.nist.gov/vuln/detail/CVE-2018-12126\nhttps://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00233.html"], "statement": "Red Hat Product Security is aware of this issue.
