  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2015-8962: Double free vulnerability in the sg_common_write function
 in drivers/scsi/sg.c in the Linux kernel allowed local users to gain
 privileges or cause a denial of service (memory corruption and system
 crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).
- CVE-2015-8963: Race condition in kernel/events/core.c in the Linux
 kernel allowed local users to gain privileges or cause a denial of
 service (use-after-free) by leveraging incorrect handling of an swevent
 data structure during a CPU unplug operation (bnc#1010502).
- CVE-2015-8964: The tty_set_termios_ldisc function in
 drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to
 obtain sensitive information from kernel memory by reading a tty data
 structure (bnc#1010507).
- CVE-2016-10088: The sg implementation in the Linux kernel did not
 properly restrict write operations in situations where the KERNEL_DS
 option is set, which allowed local users to read or write to arbitrary
 kernel memory locations or cause a denial of service (use-after-free) by
 leveraging access to a /dev/sg device, related to block/bsg.c and
 drivers/scsi/sg.c. NOTE: this vulnerability exists because of an
 incomplete fix for CVE-2016-9576 (bnc#1017710).
- CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop
 function in block/genhd.c in the Linux kernel allowed local users to
 gain privileges by leveraging the execution of a certain stop operation
 even if the corresponding start operation had failed (bnc#1010716).
- CVE-2016-7911: Race condition in the get_task_ioprio function in
 block/ioprio.c in the Linux kernel allowed local users to gain
 privileges or cause a denial of service (use-after-free) via a crafted
 ioprio_get system call (bnc#1010711).
- CVE-2016-7913: The xc2028_set_config function in
 drivers/media/tuners/tuner-xc2028.c in the Linux kernel allowed local
 users to gain privileges or cause a denial of service (use-after-free)
 via vectors involving omission of the firmware name from a certain data
 structure (bnc#1010478).
- CVE-2016-7914: The assoc_array_insert_into_terminal_node function in
 lib/assoc_array.c in the Linux kernel did not check whether a slot is a
 leaf, which allowed local users to obtain sensitive information from
 kernel memory or cause a denial of service (invalid pointer dereference
 and out-of-bounds read) via an application that uses associative-array
 data structures, as demonstrated by the keyutils test suite
 (bnc#1010475).
- CVE-2016-8399: An elevation of privilege vulnerability in the kernel
 networking subsystem could enable a local malicious application to
 execute arbitrary code within the context of the kernel. This issue is
 rated as Moderate because it first requires compromising a privileged
 ... [Please see the references for more information on the vulnerabilities]");
