Description:

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).
  • CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).
  • CVE-2019-18683: An issue was discovered in drivers/media/platform/vivid in the Linux kernel. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).
  • CVE-2019-18809: A memory leak in the af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1156258).
  • CVE-2019-19062: A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures (bnc#1157333).
  • CVE-2019-19057: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures (bnc#1157197).
  • CVE-2019-19056: A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures (bnc#1157197).
  • CVE-2019-19068: A memory leak in the rtl8xxxu_submit_int_urb() function in drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures (bnc#1157307).
  • CVE-2019-19063: Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157298).
  • CVE-2019-19227: In the AppleTalk subsystem in the Linux kernel there was a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client (bnc#1157678).
  • CVE-2019-19065: A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures (bnc#1157191).
  • CVE-2019-19077: A memory leak in the bnxt_re_create_srq() function in drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering copy to udata failures (bnc#1157171).
  • CVE-2019-19052: A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures (bnc#1157324).
  • CVE-2019-19067: Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering mfd_add_hotplug_devices() or pm_genpd_add_device() failures (bsc#1157180).
  • CVE-2019-19060: A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157178).
  • CVE-2019-19049: A memory leak in the unittest_data_add() function in drivers/of/unittest.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering of_fdt_unflatten_tree() failures (bsc#1157173).
  • CVE-2019-19075: A memory leak in the ca8210_probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering ca8210_get_platform_data() failures (bnc#1157162).
  • CVE-2019-19058: A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures (bnc#1157145).
  • CVE-2019-19074: A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) (bnc#1157143).
  • CVE-2019-19073: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering wait_for_completion_timeout() failures. This affects the htc_config_pipe_credits() function, the htc_setup_complete() function, and the htc_connect_service() function (bnc#1157070).
  • CVE-2019-15916: An issue was discovered in the Linux kernel There was a memory leak in register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service (bnc#1149448).
  • CVE-2019-16231: drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 did not check the alloc_workqueue return value, leading to a NULL pointer dereference (bnc#1150466).
  • CVE-2019-18805: An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel There was a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact (bnc#1156187).
  • CVE-2019-17055: base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel did not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket (bnc#1152782).

The following non-security bugs were fixed:

  • ACPI / LPSS: Exclude I2C busses shared with PUNIT from pmc_atom_d3_mask (bsc#1051510).
  • ACPI / SBS: Fix rare oops when removing modules (bsc#1051510).
  • ACPICA: Never run _REG on system_memory and system_IO (bsc#1051510).
  • ACPICA: Use %d for signed int print formatting instead of %u (bsc#1051510).
  • ALSA: 6fire: Drop the dead code (git-fixes).
