  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.136 to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-5848: In the function wmi_set_ie(), the length validation code
 did not handle unsigned integer overflow properly. As a result, a large
 value of the 'ie_len' argument could have caused a buffer overflow
 (bnc#1097356).
- CVE-2017-18249: The add_free_nid function did not properly track an
 allocated nid, which allowed local users to cause a denial of service
 (race condition) or possibly have unspecified other impact via
 concurrent threads (bnc#1087036).
- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and
 AVX registers) between processes. These registers might contain
 encryption keys when doing SSE accelerated AES enc/decryption
 (bsc#1087086).
- CVE-2017-18241: Prevent a NULL pointer dereference by using a
 noflush_merge
 option that triggers a NULL value for a flush_cmd_control data structure
 (bnc#1086400).
- CVE-2017-17741: The KVM implementation in the Linux kernel allowed
 attackers to obtain potentially sensitive information from kernel
 memory, aka a write_mmio stack-based out-of-bounds read (bnc#1073311).
- CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c, a memory
 corruption bug in JFS can be triggered by calling setxattr twice with
 two different extended attribute names on the same file. This
 vulnerability can be triggered by an unprivileged user with the ability
 to create files and execute programs. A kmalloc call is incorrect,
 leading to slab-out-of-bounds in jfs_xattr (bnc#1097234).
The following non-security bugs were fixed:
- 8139too: Use disable_irq_nosync() in rtl8139_poll_controller()
 (bnc#1012382).
- ACPI: acpi_pad: Fix memory leak in power saving threads (bnc#1012382).
- ACPICA: acpi: acpica: fix acpi operand cache leak in nseval.c
 (bnc#1012382).
- ACPICA: Events: add a return on failure from acpi_hw_register_read
 (bnc#1012382).
- ACPI: processor_perflib: Do not send _PPC change notification if not
 ready (bnc#1012382).
- affs_lookup(): close a race with affs_remove_link() (bnc#1012382).
- af_key: Always verify length of provided sadb_key (bnc#1012382).
- aio: fix io_destroy(2) vs. lookup_ioctx() race (bnc#1012382).
- alsa: control: fix a redundant-copy issue (bnc#1012382).
- alsa: hda: Add Lenovo C50 All in one to the power_save blacklist
 (bnc#1012382).
- alsa: hda - Use IS_REACHABLE() for dependency on input (bnc#1012382
 bsc#1031717).
- alsa: timer: Call notifier in the same spinlock (bnc#1012382 bsc#973378).
- alsa: timer: Fix pause event notification (bnc#1012382 bsc#973378).
- alsa: usb: mixer: volume quirk for CM102-A+/102S+ (bnc#1012382).
- alsa: vmaster: Propagate slave error (bnc#1012382).
- arc: Fix malformed ARC_EMUL_UNALIGNED default (bnc#1012382).
- arm64: Add ARCH_WORKAROUND_2 probing (bsc#1085308).
- arm64: Add per-cpu infrastructure to call ... [Please see the references for more information on the vulnerabilities]");
