  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP4 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).

CVE-2019-16232: Fixed a NULL pointer dereference in
 drivers/net/wireless/marvell/libertas/if_sdio.c, which did not check the
 alloc_workqueue return value (bnc#1150465).

CVE-2019-16234: Fixed a NULL pointer dereference in
 drivers/net/wireless/intel/iwlwifi/pcie/trans.c, which did not check the
 alloc_workqueue return value (bnc#1150452).

CVE-2019-17056: Added enforcement of CAP_NET_RAW in llcp_sock_create in
 net/nfc/llcp_sock.c in the AF_NFC network module, the lack of which
 allowed unprivileged users to create a raw socket, aka CID-3a359798b176
 (bnc#1152788).

CVE-2019-17133: Fixed a buffer overflow in cfg80211_mgd_wext_giwessid in
 net/wireless/wext-sme.c caused by long SSID IEs (bsc#1153158).

CVE-2019-17666: Added an upper-bound check in rtl_p2p_noa_ie in
 drivers/net/wireless/realtek/rtlwifi/ps.c, the lack of which could have
 led to a buffer overflow (bnc#1154372).

The following non-security bugs were fixed:
9p: avoid attaching writeback_fid on mmap with type PRIVATE
 (bsc#1051510).

ACPI / CPPC: do not require the _PSD method (bsc#1051510).

ACPI: CPPC: Set pcc_data[pcc_ss_id] to NULL in
 acpi_cppc_processor_exit() (bsc#1051510).

ACPI: custom_method: fix memory leaks (bsc#1051510).

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

ACPI / processor: do not print errors for processorIDs == 0xff
 (bsc#1051510).

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

act_mirred: Fix mirred_init_module error handling (bsc#1051510).
