  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.126 to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-1091: In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service (bnc#1087231).
- CVE-2018-7740: The resv_map_release function in mm/hugetlb.c allowed local users to cause a denial of service (BUG) via a crafted application that made mmap system calls and has a large pgoff argument to the remap_file_pages system call (bnc#1084353).
- CVE-2018-8043: The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c did not validate certain resource availability, which allowed local users to cause a denial of service (NULL pointer dereference) (bnc#1084829).
- CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c allowed local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl. (bnc#1088241)
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious NCPFS servers to crash the kernel or execute code (bnc#1086162).

- acpi / pmic: xpower: Fix power_table addresses (bnc#1012382).
- acpi/processor: Fix error handling in __acpi_processor_start() (bnc#1012382).
- acpi/processor: Replace racy task affinity logic (bnc#1012382).
- add mainline tag to various patches to be able to get further work done
- af_iucv: enable control sends in case of SEND_SHUTDOWN (bnc#1085507, LTC#165135).
- agp/intel: Flush all chipset writes after updating the GGTT (bnc#1012382).
- ahci: Add PCI-id for the Highpoint Rocketraid 644L card (bnc#1012382).
- alsa: aloop: Fix access to not-yet-ready substream via cable (bnc#1012382).
