    Affected Products:
                        SUSE Linux Enterprise Server for SAP 12-SP1
                        SUSE Linux Enterprise Server 12-SP1-LTSS
                        SUSE Linux Enterprise Module for Public Cloud 12
    ______________________________________________________________________________
    
       An update that solves 7 vulnerabilities and has 13 fixes is
       now available.
    
    Description:
    
       The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
       security and bugfixes.
    
       The following security bugs were fixed:
    
       - CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
       - CVE-2018-20855: An issue was discovered in create_qp_common in
         drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never
         initialized, resulting in a leak of stack memory to userspace
         (bsc#1143045).
       - CVE-2019-14284: The drivers/block/floppy.c allowed a denial of service
         by setup_format_params division-by-zero. Two consecutive ioctls can
         trigger the bug: the first one should set the drive geometry with .sect
         and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy
         format operation should be called. It can be triggered by an
         unprivileged local user even when a floppy disk has not been inserted.
         NOTE: QEMU creates the floppy device by default (bsc#1143189).
       - CVE-2019-14283: The function set_geometry in drivers/block/floppy.c did
         not validate the sect and head fields, as demonstrated by an integer
         overflow and out-of-bounds read. It can be triggered by an unprivileged
         local user when a floppy disk has been inserted. NOTE: QEMU creates the
         floppy device by default (bsc#1143191).
       - CVE-2019-11810: A NULL pointer dereference can occur when
         megasas_create_frame_pool() fails in megasas_alloc_cmds() in
         drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of
         Service, related to a use-after-free (bsc#1134399).
       - CVE-2019-13648: In the Linux kernel on the powerpc platform, when
         hardware transactional memory is disabled, a local user can cause a
         denial of service (TM Bad Thing exception and system crash) via a
         sigreturn() system call that sends a crafted signal frame. This affects
         arch/powerpc/kernel/signal_32.c and arch/powerpc/kernel/signal_64.c
         (bnc#1142254).
       - CVE-2019-13631: In parse_hid_report_descriptor in
         drivers/input/tablet/gtco.c, a malicious USB device can send an HID
         report that triggers an out-of-bounds write during generation of
         debugging messages (bsc#1142023).
    
       The following non-security bugs were fixed:
    
       - bcache: Revert "bcache: fix high CPU occupancy during journal"
         (bsc#1140652, bsc#1144288).
       - bcache: Revert "bcache: free heap cache_set->flush_btree in
         bch_journal_free" (bsc#1140652, bsc#1144288).
       - bcache: add reclaimed_journal_buckets to struct cache_set (bsc#1140652,
         bsc#1144288).
       - bcache: fix race in btree_flush_write() (bsc#1140652, bsc#1144288).
       - bcache: fix stack corruption by PRECEDING_KEY() (bsc#1130972,
         bsc#1144257).
       - bcache: only set BCACHE_DEV_WB_RUNNING when cached device attached
         (bsc#1130972, bsc#1144273).
       - bcache: performance improvement for btree_flush_write() (bsc#1140652,
         bsc#1144288).
       - bcache: remove retry_flush_write from struct cache_set (bsc#1140652,
         bsc#1144288).
       - mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing
         (bsc#1142098).
       - powerpc/watchpoint: Restore NV GPRs while returning from exception
         (bsc#1140945, bsc#1141401, bsc#1141402, bsc#1141452, bsc#1141453,
         bsc#1141454).
       - xen-netfront: use napi_complete() correctly to prevent Rx stalling
         (bsc#1138744).
