  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP4 kernel for Azure was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).
- CVE-2018-18445: Faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit right shifts (bnc#1112372).
- CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).
- CVE-2017-18224: fs/ocfs2/aops.c omits use of a semaphore and consequently has a race condition for access to the extent tree during read operations in DIRECT mode, which allowed local users to cause a denial of service (BUG) by modifying a certain e_cpos field (bnc#1084831).
- CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674).

The following non-security bugs were fixed:

- acpi, nfit: Prefer _DSM over _LSR for namespace label reads (bsc#112128).
- acpi / processor: Fix the return value of acpi_processor_ids_walk() (bsc#1051510).
- aio: fix io_destroy(2) vs. lookup_ioctx() race (git-fixes).
- alsa: hda: Add 2 more models to the power_save blacklist (bsc#1051510).
- alsa: hda - Add mic quirk for the Lenovo G50-30 (17aa:3905) (bsc#1051510).
- alsa: hda - Add quirk for ASUS G751 laptop (bsc#1051510).
- alsa: hda - Fix headphone pin config for ASUS G751 (bsc#1051510).
- alsa: hda: fix unused variable warning (bsc#1051510).
- alsa: hda/realtek - Cannot adjust speaker's volume on Dell XPS 27 7760 (bsc#1051510).
- alsa: hda/realtek - Fix the problem of the front MIC on the Lenovo M715 (bsc#1051510).
- alsa: usb-audio: update quirk for B&W PX to remove microphone (bsc#1051510).
- apparmor: Check buffer bounds when mapping permissions mask (git-fixes).
- ARM: bcm2835: Add GET_THROTTLED firmware property (bsc#1108468).
- ASoC: intel: skylake: Add missing break in skl_tplg_get_token() (bsc#1051510).
- ASoC: Intel: Skylake: Reset the controller in probe (bsc#1051510).
- ASoC: rsnd: adg: care clock-frequency size (bsc#1051510).
- ASoC: rsnd: do not fallback to PIO mode when -EPROBE_DEFER (bsc#1051510).
- ASoC: rt5514: Fix the issue of the delay volume applied again (bsc#1051510).
- ASoC: sigmadsp: safeload should not have lower byte limit (bsc#1051510).
- ASoC: wm8804: Add ACPI support (bsc#1051510).
- ath10k: fix kernel panic ... [Please see the references for more information on the vulnerabilities]");
