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

CVE-2019-9213: expand_downwards in mm/mmap.c lacks 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-2019-8980: A memory leak in the kernel_read_file function in
 fs/exec.c allowed attackers to cause a denial of service (memory
 consumption) by triggering vfs_read failures (bnc#1126209).

CVE-2019-3819: A flaw was found in the function hid_debug_events_read()
 in drivers/hid/hid-debug.c file which may enter an infinite loop with
 certain parameters passed from a userspace. A local privileged user
 ('root') can cause a system lock up and a denial of service.
 (bnc#1123161).

CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglects to set a
 NULL value for a certain structure member, which leads to a
 use-after-free in sockfs_setattr (bnc#1125907).

CVE-2019-7308: kernel/bpf/verifier.c performed undesirable out-of-bounds
 speculation on pointer arithmetic in various cases, including cases of
 different branches with different state or limits to sanitize, leading
 to side-channel attacks (bnc#1124055).

CVE-2019-3459, CVE-2019-3460: The Bluetooth stack suffered from two
 remote information leak vulnerabilities in the code that handles
 incoming L2cap configuration packets (bsc#1120758).

CVE-2019-7221: The KVM implementation had a Use-after-Free problem
 (bnc#1124732).

CVE-2019-7222: The KVM implementation had an Information Leak
 (bnc#1124735).

CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled
 reference counting because of a race condition, leading to a
 use-after-free (bnc#1124728).

CVE-2018-20669: Missing access control checks in ioctl of gpu/drm/i915
 driver were fixed which might have lead to information leaks.
 (bnc#1122971).

The following non-security bugs were fixed:
6lowpan: iphc: reset mac_header after decompress to fix panic
 (bsc#1051510).

9p: clear dangling pointers in p9stat_free (bsc#1051510).

9p locks: fix glock.client_id leak in do_lock (bsc#1051510).

9p/net: fix memory leak in p9_client_create (bsc#1051510).

9p/net: put a lower bound on msize (bsc#1051510).

9p: use inode->i_lock to protect i_size_write() under 32-bit
 (bsc#1051510).

acpi/APEI: Clear GHES block_status before panic() (bsc#1051510).

acpi/device_sysfs: Avoid OF modalias creation for removed device
 (bsc#1051510).

acpi/nfit: Block function zero DSMs (bsc#1051510).

acpi/nfit: Fix Address Range Scrub completion tracking (bsc#1124969).

acpi/nfit: Fix bus command validation (bsc#1051510).

acpi/nfit: Fix command-supported detection ... [Please see the references for more information on the vulnerabilities]");
