  - Array index error in the tcm_vhost_make_tpg function in     drivers/vhost/scsi.c in the Linux kernel before 4.0     might allow guest OS users to cause a denial of service     (memory corruption) or possibly have unspecified other     impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl     call. NOTE: the affected function was renamed to     vhost_scsi_make_tpg before the vulnerability was     announced.(CVE-2015-4036)

  - The ecryptfs_privileged_open function in     fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3     allows local users to gain privileges or cause a denial     of service (stack memory consumption) via vectors     involving crafted mmap calls for /proc pathnames,     leading to recursive pagefault handling.(CVE-2016-1583)

  - It was found that SCSI driver in the Linux kernel can     improperly access userspace memory outside the provided     buffer. A local privileged attacker could potentially     use this flaw to expose information from the kernel     memory.(CVE-2017-13168)

  - The acpi_ds_create_operands() function in     drivers/acpi/acpica/dsutils.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13693)

  - The acpi_ps_complete_final_op() function in     drivers/acpi/acpica/psobject.c in the Linux kernel     through 4.12.9 does not flush the node and node_ext     caches and causes a kernel stack dump, which allows     local users to obtain sensitive information from kernel     memory and bypass the KASLR protection mechanism (in     the kernel through 4.9) via a crafted ACPI     table.(CVE-2017-13694)

  - The acpi_ns_evaluate() function in     drivers/acpi/acpica/nseval.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13695)

  - The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h     in the Linux kernel before 4.13.2 does not verify that     a filesystem has a realtime device, which allows local     users to cause a denial of service (NULL pointer     dereference and OOPS) via vectors related to setting an     RHINHERIT flag on a directory.(CVE-2017-14340)

  - The xfs_bmap_extents_to_btree function in     fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through     4.16.3 allows local users to cause a denial of service     (xfs_bmapi_write NULL pointer dereference) via a     crafted xfs image.(CVE-2018-10323)

  - A flaw was found in the Linux kernel ext4 filesystem.
    An out-of-bound access is possible in the     ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)

  - The pcpu_embed_first_chunk function in mm/percpu.c in     the Linux kernel through 4.14.14 allows local users to     obtain sensitive address information by reading dmesg     data from a(CVE-2018-5995)

  - Memory leak in the irda_bind function in     net/irda/af_irda.c and later in     drivers/staging/irda/net/af_irda.c in the Linux kernel     before 4.17 allows local users to cause a denial of     service (memory consumption) by repeatedly binding an     AF_IRDA socket.(CVE-2018-6554)

  - A NULL pointer dereference was found in the     net/rds/rdma.c __rds_rdma_map() function in the Linux     kernel before 4.14.7 allowing local attackers to cause     a system panic and a denial-of-service, related to     RDS_GET_MR and RDS_GET_MR_FOR_DEST.(CVE-2018-7492)

  - ** DISPUTED ** Race condition in the     store_int_with_restart() function in     arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel     through 4.15.7 allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck<cpu     number> directory. NOTE: a third party has indicated     that this report is not security     relevant.(CVE-2018-7995)

  - Non-optimized code for key handling of shared futexes     was found in the Linux kernel in the form of unbounded     contention time due to the page lock for real-time     users. Before the fix, the page lock was an     unnecessarily heavy lock for the futex path that     protected too much. After the fix, the page lock is     only required in a specific corner case.(CVE-2018-9422)

  - A memory leak in the ccp_run_sha_cmd() function in     drivers/crypto/ccp/ccp-ops.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of     service (memory consumption), aka     CID-128c66429247.(CVE-2019-18808)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 4.14.192-147.314. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1480 advisory.

    2024-06-19: CVE-2020-14356 was added to this advisory.

    The Serial Attached SCSI (SAS) implementation in the Linux kernel mishandles a mutex within libsas. This     allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.
    (CVE-2017-18232)

    The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel can cause a NULL     pointer dereference in xfs_bmapi_write function. An attacker could trick a legitimate user or a privileged     attacker could exploit this by mounting a crafted xfs filesystem image to cause a kernel panic and thus a     denial of service. (CVE-2018-10323)

    The Linux kernel was found vulnerable to a NULL pointer dereference in the drivers/net/phy/mdio-bcm-     unimac.c:unimac_mdio_probe() function caused by an unchecked return value from the platform_get_resource()     function. A successful flaw exploitation can cause a system panic and a denial of service. This flaw is     believed not to be an attacker triggerable as bad return value can be caused by hardware misconfiguration.
    (CVE-2018-8043)

    A flaw was found in the AMD Cryptographic Co-processor driver in the Linux kernel. An attacker, able to     send invalid SHA type commands, could cause the system to crash. The highest threat from this     vulnerability is to system availability. (CVE-2019-18808)

    A flaw was found in the Linux kernel. The CX23888 Integrated Consumer Infrared Controller probe code     handles resource cleanup low memory conditions. A local attacker able to induce low memory conditions     could use this flaw to crash the system. The highest threat from this vulnerability is to system     availability. (CVE-2019-19054)

    A memory leak flaw was found in the adis_update_scan_mode_burst() function in     drivers/iio/imu/adis_buffer.c in the Linux kernel. This flaw allows attackers to cause a denial of     service. (CVE-2019-19061)

    Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel through 5.3.11 allow     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, aka CID-853acf7caf10. (CVE-2019-19073)

    A memory leak in the ath9k_wmi_cmd() function in drivers/net/wireless/ath/ath9k/wmi.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-728c1e2a05e4.
    (CVE-2019-19074)

    A flaw was found in the way Linux kernel's KVM hypervisor handled deferred TLB flush requests from guest.
    A race condition may occur between the guest issuing a deferred TLB flush request to KVM, and then KVM     handling and acknowledging it. This may result in invalid address translations from TLB being used to     access guest memory, leading to a potential information leakage issue. An attacker may use this flaw to     access guest memory locations that it should not have access to. (CVE-2019-3016)

    In the Android kernel in F2FS driver there is a possible out of bounds read due to a missing bounds check.
    This could lead to local information disclosure with system execution privileges needed. User interaction     is not needed for exploitation. (CVE-2019-9445)

    A flaw was found in the ZRAM kernel module, where a user with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device.
    With this vulnerability, continually reading the device may consume a large amount of system memory and     cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making     the system inoperable. (CVE-2020-10781)

    A flaw was discovered in the XFS source in the Linux kernel. This flaw allows an attacker with the ability     to mount an XFS filesystem, to trigger a denial of service while attempting to sync a file located on an     XFS v5 image with crafted metadata. (CVE-2020-12655)

    A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found     in the way when reboot the system. A local user could use this flaw to crash the system or escalate their     privileges on the system. (CVE-2020-14356)

    In the Linux kernel 4.4 through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak,     aka CID-28ebeb8db770. (CVE-2020-15393)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The xfs_bmap_extents_to_btree function in     fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through     4.16.3 allows local users to cause a denial of service     (xfs_bmapi_write NULL pointer dereference) via a     crafted xfs image.(CVE-2018-10323)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause a use-after-free in     ext4_xattr_set_entry function and a denial of service     or unspecified other impact may occur by renaming a     file in a crafted ext4 filesystem     image.(CVE-2018-10879)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in     jbd2_journal_dirty_metadata(), a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image. (CVE-2018-10883)

  - The Linux kernel was found vulnerable to an integer     overflow in the     drivers/video/fbdev/uvesafb.c:uvesafb_setcmap()     function. The vulnerability could result in local     attackers being able to crash the kernel or potentially     elevate privileges.(CVE-2018-13406)

  - It was found that paravirt_patch_call/jump() functions     in the arch/x86/kernel/paravirt.c in the Linux kernel     mishandles certain indirect calls, which makes it     easier for attackers to conduct Spectre-v2 attacks     against paravirtualized guests. (CVE-2018-15594)

  - A flaw was found in the Linux kernel's NFS     implementation. An attacker, who is able to mount an     exported NFS filesystem, is able to trigger a null     pointer dereference by using an invalid NFS sequence.
    This can panic the machine and deny access to the NFS     server. Any outstanding disk writes to the NFS server     will be lost. (CVE-2018-16871)

  - A vulnerability was found in the Linux kernelaEURtms     floppy disk driver implementation. A local attacker     with access to the floppy device could call     set_geometry in drivers/block/floppy.c, which does not     validate the sect and head fields, causing an integer     overflow and out-of-bounds read. This flaw may crash     the system or allow an attacker to gather information     causing subsequent successful attacks. (CVE-2019-14283)

  - A vulnerability was found in the Linux kernelaEURtms     floppy disk driver implementation. A local attacker     with access to the floppy disk device file (/dev/fd0     through to /dev/fdN) can create a situation that causes     the kernel to divide by zero. This requires two     consecutive ioctl calls to be issued. The first ioctl     call sets the sector and rate values, and the second     ioctl is the call to format the floppy disk to the     appropriate values. This flaw can cause the system to     divide by zero and panic the host. No media (floppy) is     required to be inserted for this attack to work     properly.(CVE-2019-14284)

  - In the Linux kernel through 5.2.1 on the powerpc     platform, when hardware transactional memory is     disabled, a local user can cause a denial of service     (TM Bad Thing exception and system crash) via a     sigreturn() system call that sends a crafted signal     frame. This affects arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c.(CVE-2019-13648)

  - In parse_hid_report_descriptor in     drivers/input/tablet/gtco.c in the Linux kernel through     5.2.1, a malicious USB device can send an HID report     that triggers an out-of-bounds write during generation     of debugging messages. (CVE-2019-13631)

  - An issue was discovered in drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference. (CVE-2019-12382)

  - An issue was discovered in dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop-i1/4zname, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash). (CVE-2019-12614)

  - An issue was discovered in the Linux kernel before     4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain     error case is mishandled.(CVE-2018-20856)

  - An issue was discovered in ip_ra_control in     net/ipv4/ip_sockglue.c in the Linux kernel through     5.1.5. There is an unchecked kmalloc of new_ra, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system crash). NOTE: this     is disputed because new_ra is never used if it is     NULL.(CVE-2019-12381)

  - An issue was discovered in ip6_ra_control in     net/ipv6/ipv6_sockglue.c in the Linux kernel through     5.1.5. There is an unchecked kmalloc of new_ra, which     might allow an attacker to cause a denial of service     (NULL pointer dereference and system crash). NOTE: This     has been disputed as not an issue.(CVE-2019-12378)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A buffer overflow was     discovered in tpacket_rcv() function in the Linux     kernel since v4.6-rc1 through v4.13. A number of     socket-related syscalls can be made to set up a     configuration when each packet received by a network     interface can cause writing up to 10 bytes to a kernel     memory outside of a kernel buffer. This can cause     unspecified kernel data corruption effects, including     damage of in-memory and on-disk XFS     data.(CVE-2017-14497)The qmi_wwan_bind function in     driverset/usb/qmi_wwan.c in the Linux kernel through     4.13.11 allows local users to cause a denial of service     (divide-by-zero error and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16650)A race condition flaw was found     in the way the Linux kernel's SCTP implementation     handled sctp_accept() during the processing of     heartbeat timeout events. A remote attacker could use     this flaw to prevent further connections to be accepted     by the SCTP server running on the system, resulting in     a denial of service.(CVE-2015-8767)A race condition     flaw was found in the way the Linux kernel's KVM     subsystem handled PIT (Programmable Interval Timer)     emulation. A guest user who has access to the PIT I/O     ports could use this flaw to crash the     host.(CVE-2014-3611)The Linux kernel is vulnerable to a     memory leak in the     driverset/wireless/mac80211_hwsim.c:hwsim_new_radio_nl(     ) function. An attacker could exploit this to cause a     potential denial of service.(CVE-2018-8087)An integer     underflow flaw was found in the way the Linux kernel's     Stream Control Transmission Protocol (SCTP)     implementation processed certain COOKIE_ECHO packets.
    By sending a specially crafted SCTP packet, a remote     attacker could use this flaw to prevent legitimate     connections to a particular SCTP server socket to be     made.(CVE-2014-4667)The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel through 4.13.11 allows local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16536)The     snd_usb_create_streams function in sound/usb/card.c in     the Linux kernel, before 4.13.6, allows local users to     cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)A flaw was     found in the Linux kernel's random number generator     API. A null pointer dereference in the rngapi_reset     function may result in denial of service, crashing the     system.(CVE-2017-15116)The __netlink_deliver_tap_skb     function in netetlink/af_netlink.c in the Linux kernel,     through 4.14.4, does not restrict observations of     Netlink messages to a single net namespace, when     CONFIG_NLMON is enabled. This allows local users to     obtain sensitive information by leveraging the     CAP_NET_ADMIN capability to sniff an nlmon interface     for all Netlink activity on the     system.(CVE-2017-17449)arch/arm64/kernel/perf_event.c     in the Linux kernel before 4.1 on arm64 platforms     allows local users to gain privileges or cause a denial     of service (invalid pointer dereference) via vectors     involving events that are mishandled during a span of     multiple HW PMUs.(CVE-2015-8955)The aac_compat_ioctl     function in drivers/scsi/aacraid/linit.c in the Linux     kernel before 3.11.8 does not require the CAP_SYS_RAWIO     capability, which allows local users to bypass intended     access restrictions via a crafted ioctl     call.(CVE-2013-6383)Linux kernel before version     4.16-rc7 is vulnerable to a null pointer dereference in     dccp_write_xmit() function in net/dccp/output.c in that     allows a local user to cause a denial of service by a     number of certain crafted system     calls.(CVE-2018-1130)The Linux kernel is vulerable to a     use-after-free flaw when Transformation User     configuration interface(CONFIG_XFRM_USER) compile-time     configuration were enabled. This vulnerability occurs     while closing a xfrm netlink socket in     xfrm_dump_policy_done. A user/process could abuse this     flaw to potentially escalate their privileges on a     system.(CVE-2017-16939)A vulnerability was found in the     Linux kernel in function rds_inc_info_copy of file     net/rds/recv.c. The last field 'flags' of object     'minfo' is not initialized. This can leak data     previously at the flags location to     userspace.(CVE-2016-5244)A flaw was found in the     kernel's ACPI interpreter when it does not flush the     operand cache and causes a kernel stack dump. This     allows local users to obtain sensitive information from     kernel memory and bypass the KASLR protection     mechanism.(CVE-2017-13693)It was found that     kernel/events/core.c in the Linux kernel mishandles     counter grouping, which allows local users to gain     privileges via a crafted application, related to the     perf_pmu_register and perf_event_open     functions.(CVE-2015-9004)The xfs_bmap_extents_to_btree     function in fs/xfs/libxfs/xfs_bmap.c in the Linux     kernel through 4.16.3 allows local users to cause a     denial of service (xfs_bmapi_write NULL pointer     dereference) via a crafted xfs     image.(CVE-2018-10323)The lrw_crypt() function in     'crypto/lrw.c' in the Linux kernel before 4.5 allows     local users to cause a system crash and a denial of     service by the NULL pointer dereference via accept(2)     system call for AF_ALG socket without calling setkey()     first to set a cipher key.(CVE-2015-8970)The IPv6     fragmentation implementation in the Linux kernel does     not consider that the nexthdr field may be associated     with an invalid option, which allows local users to     cause a denial of service (out-of-bounds read and BUG)     or possibly have unspecified other impact via crafted     socket and send system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-9074)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

  - CVE-2017-5715     Multiple researchers have discovered a vulnerability in     various processors supporting speculative execution,     enabling an attacker controlling an unprivileged process     to read memory from arbitrary addresses, including from     the kernel and all other processes running on the     system.

  This specific attack has been named Spectre variant 2 (branch target   injection) and is mitigated for the x86 architecture (amd64 and   i386) by using the 'retpoline' compiler feature which allows   indirect branches to be isolated from speculative execution.

  - CVE-2017-5753     Multiple researchers have discovered a vulnerability in     various processors supporting speculative execution,     enabling an attacker controlling an unprivileged process     to read memory from arbitrary addresses, including from     the kernel and all other processes running on the     system.

  This specific attack has been named Spectre variant 1 (bounds-check   bypass) and is mitigated by identifying vulnerable code sections   (array bounds checking followed by array access) and replacing the   array access with the speculation-safe array_index_nospec()   function.

  More use sites will be added over time.

  - CVE-2017-17975     Tuba Yavuz reported a use-after-free flaw in the     USBTV007 audio-video grabber driver. A local user could     use this for denial of service by triggering failure of     audio registration.

  - CVE-2017-18193     Yunlei He reported that the f2fs implementation does not     properly handle extent trees, allowing a local user to     cause a denial of service via an application with     multiple threads.

  - CVE-2017-18216     Alex Chen reported that the OCFS2 filesystem failed to     hold a necessary lock during nodemanager sysfs file     operations, potentially leading to a NULL pointer     dereference. A local user could use this for denial of     service.

  - CVE-2017-18218     Jun He reported a use-after-free flaw in the Hisilicon     HNS ethernet driver. A local user could use this for     denial of service.

  - CVE-2017-18222     It was reported that the Hisilicon Network Subsystem     (HNS) driver implementation does not properly handle     ethtool private flags. A local user could use this for     denial of service or possibly have other impact.

  - CVE-2017-18224     Alex Chen reported that the OCFS2 filesystem omits the     use of a semaphore and consequently has a race condition     for access to the extent tree during read operations in     DIRECT mode. A local user could use this for denial of     service.

  - CVE-2017-18241     Yunlei He reported that the f2fs implementation does not     properly initialise its state if the 'noflush_merge'     mount option is used. A local user with access to a     filesystem mounted with this option could use this to     cause a denial of service.

  - CVE-2017-18257     It was reported that the f2fs implementation is prone to     an infinite loop caused by an integer overflow in the
    __get_data_block() function. A local user can use this     for denial of service via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP ioctl.

  - CVE-2018-1065     The syzkaller tool found a NULL pointer dereference flaw     in the netfilter subsystem when handling certain     malformed iptables rulesets. A local user with the     CAP_NET_RAW or CAP_NET_ADMIN capability (in any user     namespace) could use this to cause a denial of service.
    Debian disables unprivileged user namespaces by default.

  - CVE-2018-1066     Dan Aloni reported to Red Hat that the CIFS client     implementation would dereference a NULL pointer if the     server sent an invalid response during NTLMSSP setup     negotiation. This could be used by a malicious server     for denial of service.

  - CVE-2018-1068     The syzkaller tool found that the 32-bit compatibility     layer of ebtables did not sufficiently validate offset     values. On a 64-bit kernel, a local user with the     CAP_NET_ADMIN capability (in any user namespace) could     use this to overwrite kernel memory, possibly leading to     privilege escalation. Debian disables unprivileged user     namespaces by default.

  - CVE-2018-1092     Wen Xu reported that a crafted ext4 filesystem image     would trigger a null dereference when mounted. A local     user able to mount arbitrary filesystems could use this     for denial of service.

  - CVE-2018-1093     Wen Xu reported that a crafted ext4 filesystem image     could trigger an out-of-bounds read in the     ext4_valid_block_bitmap() function. A local user able to     mount arbitrary filesystems could use this for denial of     service.

  - CVE-2018-1108     Jann Horn reported that crng_ready() does not properly     handle the crng_init variable states and the RNG could     be treated as cryptographically safe too early after     system boot.

  - CVE-2018-5803     Alexey Kodanev reported that the SCTP protocol did not     range-check the length of chunks to be created. A local     or remote user could use this to cause a denial of     service.

  - CVE-2018-7480     Hou Tao discovered a double-free flaw in the     blkcg_init_queue() function in block/blk-cgroup.c. A     local user could use this to cause a denial of service     or have other impact.

  - CVE-2018-7566     Fan LongFei reported a race condition in the ALSA     (sound) sequencer core, between write and ioctl     operations. This could lead to an out-of-bounds access     or use-after-free. A local user with access to a     sequencer device could use this for denial of service or     possibly for privilege escalation.

  - CVE-2018-7740     Nic Losby reported that the hugetlbfs filesystem's mmap     operation did not properly range-check the file offset.
    A local user with access to files on a hugetlbfs     filesystem could use this to cause a denial of service.

  - CVE-2018-7757     Jason Yan reported a memory leak in the SAS     (Serial-Attached SCSI) subsystem. A local user on a     system with SAS devices could use this to cause a denial     of service.

  - CVE-2018-7995     Seunghun Han reported a race condition in the x86 MCE     (Machine Check Exception) driver. This is unlikely to     have any security impact.

  - CVE-2018-8087     A memory leak flaw was found in the hwsim_new_radio_nl()     function in the simulated radio testing tool driver for     mac80211, allowing a local user to cause a denial of     service.

  - CVE-2018-8781     Eyal Itkin reported that the udl (DisplayLink) driver's     mmap operation did not properly range-check the file     offset. A local user with access to a udl framebuffer     device could exploit this to overwrite kernel memory,     leading to privilege escalation.

  - CVE-2018-8822     Dr Silvio Cesare of InfoSect reported that the ncpfs     client implementation did not validate reply lengths     from the server. An ncpfs server could use this to cause     a denial of service or remote code execution in the     client.

  - CVE-2018-10323     Wen Xu reported a NULL pointer dereference flaw in the     xfs_bmapi_write() function triggered when mounting and     operating a crafted xfs filesystem image. A local user     able to mount arbitrary filesystems could use this for     denial of service.

  - CVE-2018-1000199     Andy Lutomirski discovered that the ptrace subsystem did     not sufficiently validate hardware breakpoint settings.
    Local users can use this to cause a denial of service,     or possibly for privilege escalation, on x86 (amd64 and     i386) and possibly other architectures.
