  script_tag(name:"insight", value:"In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-5332)

In the Linux kernel through 4.14.13, the rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic.(CVE-2018-5333)

A flaw was found in the Linux kernel's handling of loopback devices. An attacker, who has permissions to setup loopback disks, may create a denial of service or other unspecified actions.(CVE-2018-5344)

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)

Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel allows local users to cause a denial of service (kernel memory exhaustion) via multiple read accesses to files in the /sys/class/sas_phy directory.(CVE-2018-7757)

A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space.(CVE-2018-8781)

A flaw was found in the way the Linux KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.(CVE-2017-7518)

A division-by-zero in set_termios(), when debugging is enabled, was found in the Linux kernel. When the [io_ti] driver is loaded, a local unprivileged attacker can request incorrect high transfer speed in the change_port_settings() in the drivers/usb/serial/io_ti.c so that the divisor value becomes zero and causes a system crash resulting in a denial of service.(CVE-2017-18360)

It was found that the Linux kernel can hit ... [Please see the references for more information on the vulnerabilities]");
