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 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 143569 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N) CVEID: CVE-2018-1000004 DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a race condition in the sound system. A remote attacker could exploit this vulnerability to cause the system to crash. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 137756 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) 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 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 147862 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) 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. CVSS Base Score: 7.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 141112 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) 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. CVSS Base Score: 7.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 146191 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-2018-3646 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-2018-3620 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. CVSS Base Score: 7.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 148318 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-2017-15265 DESCRIPTION: Linux Kernel could allow a local attacker to gain elevated privileges on the system, caused by a use-after-free memory error in the ALSA sequencer interface (/dev/snd/seq). By persuading a victim to open a specially-crafted application, an attacker could exploit this vulnerability to execute arbitrary code on the system with elevated privileges. CVSS Base Score: 7.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 133342 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) CVEID: CVE-2017-0861 DESCRIPTION: Google Android could allow a remote attacker to gain elevated privileges on the system, caused by a flaw in the Upstream kernel audio driver. By persuading a victim to open a specially-crafted application, an attacker could exploit this vulnerability to gain elevated privileges on the system. CVSS Base Score: 7.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 135049 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) CVEID: CVE-2018-14634 DESCRIPTION: Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by an integer overflow in the create_elf_tables function. By using a specially-crafted binary file, an attacker could exploit this vulnerability to obtain full root privileges. CVSS Base Score: 7.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 150310 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) CVEID: CVE-2018-5391 DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by the improper handling of the reassembly of fragmented IPv4 and IPv6 packets by the IP implementation. By sending specially crafted IP fragments with random offsets, a remote attacker could exploit this vulnerability to exhaust all available CPU resources and cause a denial of service.
