  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to 4.4.121 to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c had an integer-overflow vulnerability that allowed local users with access to the udldrmfb driver to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space (bnc#1090643).
- CVE-2018-10124: The kill_something_info function in kernel/signal.c might have allowed local users to cause a denial of service via an INT_MIN argument (bnc#1089752).
- CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might have allowed local users to cause a denial of service by triggering an attempted use of the -INT_MIN value (bnc#1089608).
- CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c in the Linux kernel 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).
- 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-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-2018-1087: And an unprivileged KVM guest user could use this flaw to potentially escalate their privileges inside a guest. (bsc#1087088)
- CVE-2018-8897: An unprivileged system user could use incorrect set up interrupt stacks to crash the Linux kernel resulting in DoS issue. (bsc#1087088)

The following non-security bugs were fixed:

- alsa: hda/realtek - Fix speaker no sound after system resume (bsc#1031717).
- alsa: hda: Add a power_save blacklist (bnc#1012382).
- alsa: usb-audio: Add a quirck for B&W PX headphones (bnc#1012382).
- arm: dts: LogicPD Torpedo: Fix I2C1 pinmux (bnc#1012382).
- arm: mvebu: Fix broken PL310_ERRATA_753970 selects (bnc#1012382).
- kvm: mmu: Fix overlap between public and private memslots (bnc#1012382).
- Partial revert 'e1000e: Avoid receiver overrun interrupt bursts' (bsc#1075428).
- Revert 'e1000e: Separate signaling for link check/link up' (bsc#1075428).
- Revert 'led: core: Fix brightness setting when setting delay_off=0' (bnc#1012382).
- Revert 'watchdog: hpwdt: Remove legacy NMI sourcing (bsc#1085185).' This reverts commit 5d4a2355a2a1c2ec6fdf9d18b68ca0a04ff73c70.
