FEDORA-2019-34a75d7e61

The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-19081: Fixed a memory leak in the nfp_flower_spawn_vnic_reprs() could have allowed attackers to cause a denial of service (bsc#1157045).

CVE-2019-19080: Fixed four memory leaks in the nfp_flower_spawn_phy_reprs() could have allowed attackers to cause a denial of service (bsc#1157044).

CVE-2019-19067: Fixed multiple memory leaks in acp_hw_init (bsc#1157180).

CVE-2019-19060: Fixed a memory leak in the adis_update_scan_mode() which could have led to denial of service (bsc#1157178).

CVE-2019-19049: Fixed a memory leak in unittest_data_add (bsc#1157173).

CVE-2019-19075: Fixed a memory leak in the ca8210_probe() which could have led to denial of service by triggering ca8210_get_platform_data() failures (bsc#1157162).

CVE-2019-19058: Fixed a memory leak in the alloc_sgtable() which could have led to denial of service by triggering alloc_page() failures (bsc#1157145).

CVE-2019-19074: Fixed a memory leak in the ath9k_wmi_cmd() function which could have led to denial of service (bsc#1157143).

CVE-2019-19073: Fixed multiple memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c which could have led to denial of service by triggering wait_for_completion_timeout() failures (bsc#1157070).

CVE-2019-19083: Fixed multiple memory leaks in *clock_source_create() functions which could have led to denial of service (bsc#1157049).

CVE-2019-19082: Fixed multiple memory leaks in *create_resource_pool() which could have led to denial of service (bsc#1157046).

CVE-2019-15916: Fixed a memory leak in register_queue_kobjects() which might have led denial of service (bsc#1149448).

CVE-2019-0154: Fixed an improper access control in subsystem for Intel (R) processor graphics whichs may have allowed an authenticated user to potentially enable denial of service via local access (bsc#1135966).

CVE-2019-0155: Fixed an improper access control in subsystem for Intel (R) processor graphics whichs may have allowed an authenticated user to potentially enable escalation of privilege via local access (bsc#1135967).

CVE-2019-16231: Fixed a NULL pointer dereference due to lack of checking the alloc_workqueue return value (bsc#1150466).

CVE-2019-18805: Fixed an integer overflow in tcp_ack_update_rtt() leading to a denial of service or possibly unspecified other impact (bsc#1156187).

CVE-2019-17055: Enforced CAP_NET_RAW in the AF_ISDN network module to restrict unprivileged users to create a raw socket (bsc#1152782).

CVE-2019-16995: Fixed a memory leak in hsr_dev_finalize() which may have caused denial of service (bsc#1152685).

CVE-2019-16233: drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return value, leading to a NULL pointer dereference.
(bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the user space. (bsc#1144903)

CVE-2019-17666: rtlwifi: Fix potential overflow in P2P code (bsc#1154372).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW, which meant that unprivileged users could create a raw socket (bsc#1152788).

CVE-2019-14821: An out-of-bounds access issue was fixed in the kernel's kvm hypervisor. 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-2017-18595: A double free in allocate_trace_buffer was fixed (bnc#1149555).

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit 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 inject arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost functionality that translates virtqueue buffers to IOVs. A privileged guest user able to pass descriptors with invalid length to the host could use this flaw to increase their privileges on the host (bnc#1150112).

CVE-2019-9456: An out-of-bounds write in the USB monitor driver has been fixed. This issue could lead to local escalation of privilege with System execution privileges needed. (bnc#1150025).

CVE-2019-15030, CVE-2019-15031: On the powerpc platform, a local user could read vector registers of other users' processes via an interrupt (bsc#1149713).

CVE-2019-18683: An issue was discovered in drivers/media/platform/vivid. 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 allows attackers to cause a denial of service (memory consumption), aka CID-2289adbfa559 (bnc#1156258).

CVE-2019-19078: A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-b8d17e7d93d2 (bnc#1157032).

CVE-2019-18660: The Linux kernel on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).

CVE-2019-14895: A heap-based buffer overflow was discovered 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 allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).

CVE-2019-19065: A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init() failures, aka CID-34b3be18a04e (bnc#1157191).

CVE-2019-19057: Two memory leaks in the mwifiex_pcie_init_evt_ring() function in drivers/net/wireless/marvell/mwifiex/pcie.c allow attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-d10dcb615c8e (bnc#1157193).

CVE-2019-19056: A memory leak in the mwifiex_pcie_alloc_cmdrsp_buf() function in drivers/net/wireless/marvell/mwifiex/pcie.c allows attackers to cause a denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka CID-db8fd2cde932 (bnc#1157197).

CVE-2019-19063: Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113 (bnc#1157298).

CVE-2019-19046: A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c allow attackers to cause a denial of service (bsc#1157304).

CVE-2019-19068: A memory leak in the rtl8xxxu_submit_int_urb() function in drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-a2cdd07488e6 (bnc#1157307).

CVE-2019-19062: A memory leak in the crypto_report() function in crypto/crypto_user_base.c allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042 (bnc#1157333).

CVE-2019-19227: In the AppleTalk subsystem, there is 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, aka CID-9804501fa122 (bnc#1157678).

CVE-2019-11135: Aborting an asynchronous TSX operation on Intel CPUs with Transactional Memory support could be used to facilitate sidechannel information leaks out of microarchitectural buffers, similar to the previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX operation altogether (requiring CPU Microcode updates on older systems) and better flushing of microarchitectural buffers (VERW).
