  script_tag(name:"insight", value:"The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2017-18595: A double free may be caused by the function
 allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-14821: An out-of-bounds access issue was found in the way Linux
 kernel's KVM hypervisor implements the coalesced MMIO write operation.
 It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object,
 wherein write indices 'ring->first' and 'ring->last' value could be
 supplied by a host user-space process. An unprivileged host user or
 process with access to '/dev/kvm' device could use this flaw to crash
 the host kernel, resulting in a denial of service or potentially
 escalating privileges on the system (bnc#1151350).

CVE-2019-15291: There was a NULL pointer dereference caused by a
 malicious USB device in the flexcop_usb_probe function in the
 drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including
 version 5.1 permitted sufficiently low encryption key length and did not
 prevent an attacker from influencing the key length negotiation. This
 allowed practical brute-force attacks (aka 'KNOB') that could decrypt
 traffic and injected arbitrary ciphertext without the victim noticing
 (bnc#1137865 bnc#1146042).

The following non-security bugs were fixed:
ACPI: custom_method: fix memory leaks (bsc#1051510).

ACPI / PCI: fix acpi_pci_irq_enable() memory leak (bsc#1051510).

ACPI / property: Fix acpi_graph_get_remote_endpoint() name in kerneldoc
 (bsc#1051510).

alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP (bsc#1151680).

ALSA: aoa: onyx: always initialize register read value (bsc#1051510).

ALSA: firewire-tascam: check intermediate state of clock status and
 retry (bsc#1051510).

ALSA: firewire-tascam: handle error code when getting current source of
 clock (bsc#1051510).

ASoC: es8328: Fix copy-paste error in es8328_right_line_controls
 (bsc#1051510).

ASoC: Intel: Baytrail: Fix implicit fallthrough warning (bsc#1051510).

ASoC: sun4i-i2s: RX and TX counter registers are swapped (bsc#1051510).

ASoC: wm8737: Fix copy-paste error in wm8737_snd_controls (bsc#1051510).

ASoC: wm8988: fix typo in wm8988_right_line_controls (bsc#1051510).

ath10k: adjust skb length in ath10k_sdio_mbox_rx_packet (bsc#1111666).

ath9k: dynack: fix possible deadlock in ath_dynack_node_{de}init
 (bsc#1051510).

atm: iphase: Fix Spectre v1 vulnerability (networking-stable-19_08_08).

bcma: fix incorrect update of BCMA_CORE_PCI_MDIO_DATA (bsc#1051510).

blk-flush: do not run queue for requests bypassing flush (bsc#1137959).

blk-flush: use blk_mq_request_bypass_insert() (bsc#1137959).

blk-mq: do not allocate driver tag upfront for flush rq (bsc#1137959).

blk-mq: Fix memory leak in blk_mq_init_allocated_queue error handling
