Vulnerability Details

CVEID: CVE-2018-13405
DESCRIPTION: Linux Kernel could allow a local attacker to gain elevated privileges on the system, caused by a flaw in the fs/inode.c:inode_init_owner() function. An attacker could exploit this vulnerability to create files with an unintended group ownership.
CVSS Base Score: 4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/146434 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

 

CVEID: CVE-2018-5390
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by an error in the tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions. By sending specially crafted packets within ongoing TCP sessions, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/147950 for the current score
CVSS Environmental Score*: Undefined

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

CVEID: CVE-2018-3620
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 could exploit this vulnerability to leak information residing in the L1 data cache and read data belonging to different security contexts. Note: This vulnerability is also known as the "L1 Terminal Fault (L1TF)" or "Foreshadow" attack.
