  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.176 to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap
 minimum address, which made it easier for attackers to exploit kernel
 NULL pointer dereferences on non-SMAP platforms. This is related to a
 capability check for the wrong task (bnc#1128166).

CVE-2019-2024: A use-after-free when disconnecting a source was fixed
 which could lead to crashes. bnc#1129179).

The following non-security bugs were fixed:
ax25: fix possible use-after-free (bnc#1012382).

block_dev: fix crash on chained bios with O_DIRECT (bsc#1090435).

block: do not use bio->bi_vcnt to figure out segment number
 (bsc#1128893).

bnxt_re: Fix couple of memory leaks that could lead to IOMMU call traces
 (bsc#1020413).

bpf: fix replace_map_fd_with_map_ptr's ldimm64 second imm field

btrfs: ensure that a DUP or RAID1 block group has exactly two stripes
 (bsc#1128452).

ceph: avoid repeatedly adding inode to mdsc->snap_flush_list
 (bsc#1126773).

ch: add missing mutex_lock()/mutex_unlock() in ch_release()
 (bsc#1124235).

ch: fixup refcounting imbalance for SCSI devices (bsc#1124235).

copy_mount_string: Limit string length to PATH_MAX (bsc#1082943).

device property: Fix the length used in PROPERTY_ENTRY_STRING()
 (bsc#1129770).

drivers: hv: vmbus: Check for ring when getting debug info (bsc#1126389).

drm: Fix error handling in drm_legacy_addctx (bsc#1106929)

drm/nouveau/bios/ramcfg: fix missing parentheses when calculating RON
 (bsc#1106929)

drm/nouveau/pmu: do not print reply values if exec is false (bsc#1106929)

drm/radeon/evergreen_cs: fix missing break in switch statement
 (bsc#1106929)

drm/vmwgfx: Do not double-free the mode stored in par->set_mode
 (bsc#1103429)

enic: add wq clean up budget (bsc#1075697, bsc#1120691. bsc#1102959).

enic: do not overwrite error code (bnc#1012382).

fbdev: chipsfb: remove set but not used variable 'size' (bsc#1106929)

iommu/vt-d: Fix NULL pointer reference in intel_svm_bind_mm()
 (bsc#1129240).

ixgbe: fix crash in build_skb Rx code path (git-fixes).

kabi: protect struct inet_peer (kabi).

kallsyms: Handle too long symbols in kallsyms.c (bsc#1126805).

KMPs: obsolete older KMPs of the same flavour (bsc#1127155, bsc#1109137).
