An update that solves 7 vulnerabilities and has three 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-2018-5390 aka "SegmentSmack": A remote attacker even with
relatively
low bandwidth could have caused lots of CPU usage by triggering the
worst case scenario during IP and/or TCP fragment reassembly
(bsc#1102340)
- CVE-2018-7191: In the tun subsystem in the Linux kernel,
dev_get_valid_name was not called before register_netdevice. This
allowed local users to cause a denial of service (NULL pointer
dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
containing a / character. (bnc#1135603)
- CVE-2018-20836: A race condition in smp_task_timedout() and
smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead
to a use-after-free. (bnc#1134395)
- CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to
cause denial of service (a NULL pointer dereference and system crash).
(bnc#1137194)
- CVE-2019-12818: The nfc_llcp_build_tlv function in
net/nfc/llcp_commands.c may have returned NULL. If the caller did not
check for this, it would trigger a NULL pointer dereference. This would
cause denial of service. (bnc#1138293)
- CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
allowed local users to cause a denial of service or possibly have
unspecified other impact by changing the value of ioc_number between two
kernel reads of that value, aka a "double fetch" vulnerability.
(bsc#1136922)
- CVE-2019-11487: An attacker could have triggered use-after-free via page
reference count overflow on slow filesystems with at least of 140 GiB of
RAM available. (bnc#1133190)

The following non-security bugs were fixed:

- fuse: Don't access pipe->buffers without pipe_lock() (Prerequisity
for
CVE-2019-11487, bsc#1133190).
- fuse: call pipe_buf_release() under pipe lock (Prerequisity for
CVE-2019-11487, bsc#1133190).
- mm: /proc/pid/maps: Check permissions when opening proc pid maps
(bsc#1130159).
- pipe: add pipe_buf_get() helper (Prerequisity for CVE-2019-11487,
bsc#1133190).
- tcp: refine memory limit test in tcp_fragment() after CVE-2019-11478 fix
(bsc#1139751).
- x86/bugs: do not default to IBRS even on SKL (bsc#1112824).
