The following security bugs were fixed:
- CVE-2018-3620: Local attackers on baremetal systems could use
 speculative code patterns on hyperthreaded processors to read data
 present in the L1 Datacache used by other hyperthreads on the same CPU
 core, potentially leaking sensitive data. (bnc#1087081).
- CVE-2018-3646: Local attackers in virtualized guest systems could use
 speculative code patterns on hyperthreaded processors to read data
 present in the L1 Datacache used by other hyperthreads on the same CPU
 core, potentially leaking sensitive data, even from other virtual
 machines or the host system. (bnc#1089343).
- CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP packet reassembly
 could be used by remote attackers to consume lots of CPU time
 (bnc#1103097).
- CVE-2018-10876: A flaw was found in the ext4 filesystem code. A
 use-after-free is possible in ext4_ext_remove_space() function when
 mounting and operating a crafted ext4 image. (bnc#1099811)
- CVE-2018-10877: The ext4 filesystem is vulnerable to an out-of-bound
 access in the ext4_ext_drop_refs() function when operating on a crafted
 ext4 filesystem image. (bnc#1099846)
- CVE-2018-10878: A flaw was found in the ext4 filesystem. A local user
 can cause an out-of-bounds write and a denial of service or unspecified
 other impact is possible by mounting and operating a crafted ext4
 filesystem image. (bnc#1099813)
- CVE-2018-10879: A flaw was found in the ext4 filesystem. A local user
 can cause a use-after-free in ext4_xattr_set_entry function and a denial
 of service or unspecified other impact may occur by renaming a file in a
 crafted ext4 filesystem image. (bnc#1099844)
- CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds
 write in the ext4 filesystem code when mounting and writing to a crafted
 ext4 image in ext4_update_inline_data(). An attacker could use this to
 cause a system crash and a denial of service. (bnc#1099845)
- CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user
 can cause an out-of-bound access in ext4_get_group_info function, a
 denial of service, and a system crash by mounting and operating on a
 crafted ext4 filesystem image. (bnc#1099864)
- CVE-2018-10882: A flaw was found in the ext4 filesystem. A local user
 can cause an out-of-bound write in fs/jbd2/transaction.c code, a
 denial of service, and a system crash by unmounting a crafted ext4
 filesystem image. (bnc#1099849)
- CVE-2018-10883: A flaw was found in the ext4 filesystem. A local user
 can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a
 denial of service, and a system crash by mounting and operating on a
 crafted ext4 filesystem image. (bnc#1099863)
The following non-security bugs were fixed:
- acpi / lpss: Only call pwm_add_table() for Bay Trail PWM if PMIC HRV is
 2 ... [Please see the references for more information on the vulnerabilities]");
