Vulnerability Details

CVEID: CVE-2018-3639 DESCRIPTION: Multiple Intel CPU’'s could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to bypass security restrictions and gain read access to privileged memory. Note: This vulnerability is the Speculative Store Bypass (SSB), also known as Variant 4 or “SpectreNG”.
CVSS Base Score: 4.3

CVEID: CVE-2018-10901 DESCRIPTION: Linux Kernel could allow a remote attacker to gain elevated privileges on the system, caused by the failure to restore the GDT.LIMIT to the previous host value by the KVM virtualization subsystem. By sending a specially-crafted argument, an attacker could exploit this vulnerability to gain elevated privileges.
CVSS Base Score: 9.8

CVEID: CVE-2018-7566 DESCRIPTION: Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by user-supplied input. By using an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq, a local authenticated attacker could overflow a buffer and execute arbitrary code on the system.

CVEID: CVE-2018-3693 DESCRIPTION: Intel Haswell Xeon, AMD PRO and ARM Cortex A57 CPUs could allow a local authenticated attacker to obtain sensitive information, caused by a bounds check bypass in the CPU speculative branch instruction execution feature. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to cross the syscall boundary and read data from the CPU virtual memory.

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.

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.
