  script_tag(name:"insight", value:"In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition.(CVE-2018-1000004)

drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.(CVE-2017-18079)

The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.(CVE-2018-5750)

The futex_requeue function in kernel/futex.c in the Linux kernel, before 4.14.15, might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impacts by triggering a negative wake or requeue value. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-6927)

The Linux kernel, before version 4.14.3, is vulnerable to a denial of service in drivers/md/dm.c:dm_get_from_kobject() which can be caused by local users leveraging a race condition with __dm_destroy() during creation and removal of DM devices. Only privileged local users (with CAP_SYS_ADMIN capability) can directly perform the ioctl operations for dm device creation and removal and this would typically be outside the direct control of the unprivileged attacker.(CVE-2017-18203)

The madvise_willneed function in the Linux kernel allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.(CVE-2017-18208)");
