The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated 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-2018-1000204: Prevent infoleak caused by incorrect     handling of the SG_IO ioctl (bsc#1096728).

  - 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-2017-13305: Prevent information disclosure     vulnerability in encrypted-keys (bsc#1094353).

  - CVE-2018-1093: The ext4_valid_block_bitmap function     allowed attackers to cause a denial of service     (out-of-bounds read and system crash) via a crafted ext4     image because balloc.c and ialloc.c did not validate     bitmap block numbers (bsc#1087095).

  - CVE-2018-1094: The ext4_fill_super function did not     always initialize the crc32c checksum driver, which     allowed attackers to cause a denial of service     (ext4_xattr_inode_hash NULL pointer dereference and     system crash) via a crafted ext4 image (bsc#1087007).

  - CVE-2018-1092: The ext4_iget function mishandled the     case of a root directory with a zero i_links_count,     which allowed attackers to cause a denial of service     (ext4_process_freed_data NULL pointer dereference and     OOPS) via a crafted ext4 image (bsc#1087012).

  - CVE-2018-1130: NULL pointer dereference in     dccp_write_xmit() function that allowed a local user to     cause a denial of service by a number of certain crafted     system calls (bsc#1092904).

  - CVE-2018-1065: The netfilter subsystem mishandled the     case of a rule blob that contains a jump but lacks a     user-defined chain, which allowed local users to cause a     denial of service (NULL pointer dereference) by     leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability     (bsc#1083650).

  - CVE-2018-5803: Prevent error in the '_sctp_make_chunk()'     function when handling SCTP packets length that could     have been exploited to cause a kernel crash     (bnc#1083900).

  - CVE-2018-7492: Prevent NULL pointer dereference in the     net/rds/rdma.c __rds_rdma_map() function that allowed     local attackers to cause a system panic and a     denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST (bsc#1082962).

  - CVE-2018-1000199: Prevent vulnerability in     modify_user_hw_breakpoint() that could have caused a     crash and possibly memory corruption (bsc#1089895).

The update package also includes non-security fixes. See advisory for details.
