Vulnerability Details
CVEID:
CVE-2018-3646
DESCRIPTION: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by a flaw in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks and via a terminal page fault, an attacker with guest OS privilege could exploit this vulnerability to leak information residing in the L1 data cache and read data belonging to different security contexts.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/148319
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N)
CVEID:
CVE-2018-3615
DESCRIPTION: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by a flaw in the CPU speculative branch instruction execution feature and Intel software guard extensions (Intel SGX). By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to leak information residing in the L1 data cache from an enclave and read data belonging to different security contexts.
CVSS Base Score: 7.9
