The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c (CVE-2019-15505)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during     authorization of SCSI commands, which allows local users to bypass intended access restrictions via an     SG_IO ioctl call that leverages overlapping opcodes. (CVE-2012-4542)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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 :

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.(CVE-2019-19227)A memory leak in the     adis_update_scan_mode() function in     drivers/iio/imu/adis_buffer.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of     service (memory consumption), aka     CID-ab612b1daf41.(CVE-2019-19060)In the Linux kernel     before 5.3.11, there is an info-leak bug that can be     caused by a malicious USB device in the     driverset/can/usb/peak_usb/pcan_usb_core.c driver, aka     CID-f7a1337f0d29.(CVE-2019-19534)In the Linux kernel     before 5.3.11, there is a use-after-free bug that can     be caused by a malicious USB device in the     driverset/can/usb/mcba_usb.c driver, aka     CID-4d6636498c41.(CVE-2019-19529)In the Linux kernel     before 5.3.9, there is a use-after-free bug that can be     caused by a malicious USB device in the     driversfc/pn533/usb.c driver, aka     CID-6af3aa57a098.(CVE-2019-19526)In the Linux kernel     before 5.3.6, there is a use-after-free bug that can be     caused by a malicious USB device in the     driverset/ieee802154/atusb.c driver, aka     CID-7fd25e6fc035.(CVE-2019-19525)In the Linux kernel     before 5.3.9, there are multiple out-of-bounds write     bugs that can be caused by a malicious USB device in     the Linux kernel HID drivers, aka CID-d9d4b1e46d95.
    This affects drivers/hid/hid-axff.c,     drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,     drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,     drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c,     drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c,     drivers/hid/hid-tmff.c, and     drivers/hid/hid-zpff.c.(CVE-2019-19532)In the Linux     kernel before 5.2.10, there is a use-after-free bug     that can be caused by a malicious USB device in the     drivers/hid/usbhid/hiddev.c driver, aka     CID-9c09b214f30e.(CVE-2019-19527)** DISPUTED ** The     Linux kernel through 5.0.7, when CONFIG_IA32_AOUT is     enabled and ia32_aout is loaded, allows local users to     bypass ASLR on setuid a.out programs (if any exist)     because install_exec_creds() is called too late in     load_aout_binary() in fs/binfmt_aout.c, and thus the     ptrace_may_access() check has a race condition when     reading /proc/pid/stat. NOTE: the software maintainer     disputes that this is a vulnerability because ASLR for     a.out format executables has never been     supported.(CVE-2019-11191)In the Linux kernel before     5.3.12, there is a use-after-free bug that can be     caused by a malicious USB device in the     drivers/input/ff-memless.c driver, aka     CID-fa3a5a1880c9.(CVE-2019-19524)driverset/wireless/mar     vell/libertas/if_sdio.c in the Linux kernel 5.2.14 does     not check the alloc_workqueue return value, leading to     a NULL pointer     dereference.(CVE-2019-16232)driverset/fjes/fjes_main.c     in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer     dereference.(CVE-2019-16231)** DISPUTED **     drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux     kernel 5.2.14 does not check the alloc_workqueue return     value, leading to a NULL pointer dereference. NOTE: The     security community disputes this issues as not being     serious enough to be deserving a CVE     id.(CVE-2019-16229)Linux kernel CIFS implementation,     version 4.9.0 is vulnerable to a relative paths     injection in directory entry lists.(CVE-2019-10220)A     heap overflow flaw was found in the Linux kernel, all     versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi     chip driver. The vulnerability allows a remote attacker     to cause a system crash, resulting in a denial of     service, or execute arbitrary code. The highest threat     with this vulnerability is with the availability of the     system. If code execution occurs, the code will run     with the permissions of root. This will affect both     confidentiality and integrity of files on the     system.(CVE-2019-14901)The Linux kernel before 5.4.2     mishandles ext4_expand_extra_isize, as demonstrated by     use-after-free errors in __ext4_expand_extra_isize and     ext4_xattr_set_entry, related to fs/ext4/inode.c and     fs/ext4/super.c, aka CID-4ea99936a163.(CVE-2019-19767)A     heap-based buffer overflow was discovered in the Linux     kernel, all versions 3.x.x and 4.x.x before 4.18.0, 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.(CVE-2019-14895)Linux Kernel could allow a local     authenticated attacker to obtain sensitive information,     caused by a Transaction Asynchronous Abort (TAA) h/w     issue in KVM. By sending a specially-crafted request,     an attacker could exploit this vulnerability to obtain     sensitive information, and use this information to     launch further attacks against the affected     system.(CVE-2019-19338)TSX Asynchronous Abort condition     on some CPUs utilizing speculative execution may allow     an authenticated user to potentially enable information     disclosure via a side channel with local     access.(CVE-2019-11135)An out-of-bounds memory write     issue was found in the Linux Kernel, version 3.13     through 5.4, in the way the Linux kernel's KVM     hypervisor handled the 'KVM_GET_EMULATED_CPUID'     ioctl(2) request to get CPUID features emulated by the     KVM hypervisor. A user or process able to access the     '/dev/kvm' device could use this flaw to crash the     system, resulting in a denial of     service.(CVE-2019-19332)kernel/sched/fair.c in the     Linux kernel before 5.3.9, when cpu.cfs_quota_us is     used (e.g., with Kubernetes), allows attackers to cause     a denial of service against non-cpu-bound applications     by generating a workload that triggers unwanted slice     expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen     with benign workloads, it is possible that an attacker     could calculate how many stray requests are required to     force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and     ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of     the kernel it only causes mismanagement of application     execution.)(CVE-2019-19922)A stack-based buffer     overflow was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. An attacker     is able to cause a denial of service (system crash) or,     possibly execute arbitrary code, when a STA works in     IBSS mode (allows connecting stations together without     the use of an AP) and connects to another     STA.(CVE-2019-14897)A heap-based buffer overflow     vulnerability was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. A remote     attacker could cause a denial of service (system crash)     or, possibly execute arbitrary code, when the     lbs_ibss_join_existing function is called after a STA     connects to an AP.(CVE-2019-14896)In the Linux kernel     through 5.4.6, there are information leaks of     uninitialized memory to a USB device in the     driverset/can/usb/kvaser_usb/kvaser_usb_leaf.c driver,     aka CID-da2311a6385c.(CVE-2019-19947)In the Linux     kernel before 5.1, there is a memory leak in
    __feat_register_sp() in net/dccp/feat.c, which may     cause denial of service, aka     CID-1d3ff0950e2b.(CVE-2019-20096)mwifiex_tm_cmd in     driverset/wireless/marvell/mwifiex/cfg80211.c in the     Linux kernel before 5.1.6 has some error-handling cases     that did not free allocated hostcmd memory, aka     CID-003b686ace82. This will cause a memory leak and     denial of service.(CVE-2019-20095)An exploitable     denial-of-service vulnerability exists in the Linux     kernel prior to mainline 5.3. An attacker could exploit     this vulnerability by triggering AP to send IAPP     location updates for stations before the required     authentication process has completed. This could lead     to different denial-of-service scenarios, either by     causing CAM table attacks, or by leading to traffic     flapping if faking already existing clients in other     nearby APs of the same wireless infrastructure. An     attacker can forge Authentication and Association     Request packets to trigger this     vulnerability.(CVE-2019-5108)In a Linux KVM guest that     has PV TLB enabled, a process in the guest kernel may     be able to read memory locations from another process     in the same guest. This problem is limit to the host     running linux kernel 4.10 with a guest running linux     kernel 4.16 or later. The problem mainly affects AMD     processors but Intel CPUs cannot be ruled     out.(CVE-2019-3016)fsamei.c in the Linux kernel before     5.5 has a may_create_in_sticky use-after-free, which     allows local users to cause a denial of service (OOPS)     or possibly obtain sensitive information from kernel     memory, aka CID-d0cb50185ae9. One attack vector may be     an open system call for a UNIX domain socket, if the     socket is being moved to a new parent directory and its     old parent directory is being     removed.(CVE-2020-8428)There is a use-after-free     vulnerability in the Linux kernel through 5.5.2 in the     n_tty_receive_buf_common function in     drivers/tty_tty.c.(CVE-2020-8648)An issue was     discovered in the Linux kernel through 5.5.6. set_fdc     in drivers/block/floppy.c leads to a wait_til_ready     out-of-bounds read because the FDC index is not checked     for errors before assigning it, aka     CID-2e90ca68b0d2.(CVE-2020-9383)There is a     use-after-free vulnerability in the Linux kernel     through 5.5.2 in the vgacon_invert_region function in     drivers/video/console/vgacon.c.(CVE-2020-8649)There is     a use-after-free vulnerability in the Linux kernel     through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c.(CVE-2020-8647)In the Linux kernel     5.0.21, mounting a crafted ext4 filesystem image,     performing some operations, and unmounting can lead to     a use-after-free in ext4_put_super in fs/ext4/super.c,     related to dump_orphan_list in     fs/ext4/super.c.(CVE-2019-19447)A flaw was discovered     in the way that the KVM hypervisor handled instruction     emulation for an L2 guest when nested virtualisation is     enabled. Under some circumstances, an L2 guest may     trick the L0 guest into accessing sensitive L1     resources that should be inaccessible to the L2     guest.(CVE-2020-2732)In the Linux kernel before 5.3.11,     sound/core/timer.c has a use-after-free caused by     erroneous code refactoring, aka CID-e7af6307a8a5. This     is related to snd_timer_open and     snd_timer_close_locked. The timeri variable was     originally intended to be for a newly created timer     instance, but was used for a different purpose after     refactoring.(CVE-2019-19807)In the Linux kernel     5.4.0-rc2, there is a use-after-free (read) in the
    __blk_add_trace function in kernel/trace/blktrace.c     (which is used to fill out a blk_io_trace structure and     place it in a per-cpu sub-buffer).(CVE-2019-19768)In     the Linux kernel 5.0.21, mounting a crafted f2fs     filesystem image can cause a NULL pointer dereference     in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This     is related to F2FS_P_SB in     fs/f2fs/f2fs.h.(CVE-2019-19815)** DISPUTED **
    __btrfs_free_extent in fs/btrfs/extent-tree.c in the     Linux kernel through 5.3.12 calls btrfs_print_leaf in a     certain ENOENT case, which allows local users to obtain     potentially sensitive information about register values     via the dmesg program. NOTE: The BTRFS development team     disputes this issues as not being a vulnerability     because '1) The kernel provide facilities to restrict     access to dmesg - dmesg_restrict=1 sysctl option. So     it's really up to the system administrator to judge     whether dmesg access shall be disallowed or not. 2)     WARN/WARN_ON are widely used macros in the linux     kernel. If this CVE is considered valid this would mean     there are literally thousands CVE lurking in the kernel
    - something which clearly is not the     case.'(CVE-2019-19039)ext4_empty_dir in fs/ext4amei.c     in the Linux kernel through 5.3.12 allows a NULL     pointer dereference because     ext4_read_dirblock(inode,0,DIRENT_HTREE) can be     zero.(CVE-2019-19037)btrfs_root_node in     fs/btrfs/ctree.c in the Linux kernel through 5.3.12     allows a NULL pointer dereference because     rcu_dereference(root->node) can be     zero.(CVE-2019-19036)In the Linux kernel 4.19.83, there     is a use-after-free (read) in the debugfs_remove     function in fs/debugfs/inode.c (which is used to remove     a file or directory in debugfs that was previously     created with a call to another debugfs function such as     debugfs_create_file).(CVE-2019-19770)An issue was     discovered in slc_bump in driverset/can/slcan.c in the     Linux kernel through 5.6.2. It allows attackers to read     uninitialized can_frame data, potentially containing     sensitive information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)An issue was     discovered in the Linux kernel through 5.6.2.
    mpol_parse_str in mm/mempolicy.c has a stack-based     out-of-bounds write because an empty nodelist is     mishandled during mount option parsing, aka     CID-aa9f7d5172fa.(CVE-2020-11565)A flaw was found in     the Linux kernel's implementation of some networking     protocols in IPsec, such as VXLAN and GENEVE tunnels     over IPv6. When an encrypted tunnel is created between     two hosts, the kernel isn't correctly routing tunneled     data over the encrypted link rather sending the data     unencrypted. This would allow anyone in between the two     endpoints to read the traffic unencrypted. The main     threat from this vulnerability is to data     confidentiality.(CVE-2020-1749)An issue was discovered     in the stv06xx subsystem in the Linux kernel before     5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and     drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c     mishandle invalid descriptors, as demonstrated by a     NULL pointer dereference, aka     CID-485b06aadb93.(CVE-2020-11609)An issue was     discovered in the Linux kernel before 5.6.1.
    drivers/media/usb/gspca/ov519.c allows NULL pointer     dereferences in ov511_mode_init_regs and     ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d.(CVE-2020-11608)In the Linux kernel     before 5.4.12, drivers/input/input.c has out-of-bounds     writes via a crafted keycode table, as demonstrated by     input_set_keycode, aka     CID-cb222aed03d7.(CVE-2019-20636)In the Linux kernel     before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c     (aka the Xirlink camera USB driver) mishandles invalid     descriptors, aka CID-a246b4d54770.(CVE-2020-11668)An     issue was discovered in the Linux kernel through 5.6.2.
    mpol_parse_str in mm/mempolicy.c has a stack-based     out-of-bounds write because an empty nodelist is     mishandled during mount option parsing, aka     CID-aa9f7d5172fa.(CVE-2020-0067)An issue was discovered     in the Linux kernel before 5.2 on the powerpc platform.
    arch/powerpc/kernel/idle_book3s.S does not have     save/restore functionality for PNV_POWERSAVE_AMR,     PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka     CID-53a712bae5dd.(CVE-2020-11669)A flaw was found in     the Linux kernelaEUR?s implementation of GRO. This flaw     allows an attacker with local access to crash the     system.(CVE-2020-10720)A flaw was found in the Linux     kernel's implementation of the invert video code on VGA     consoles when a local attacker attempts to resize the     console, calling an ioctl VT_RESIZE, which causes an     out-of-bounds write to occur. This flaw allows a local     user with access to the VGA console to crash the     system, potentially escalating their privileges on the     system. The highest threat from this vulnerability is     to data confidentiality and integrity as well as system     availability.(CVE-2020-14331)An out-of-bounds (OOB)     memory access flaw was found in ttm_put_pages in     drivers/gpu/drm/ttm/ttm_page_alloc.c in the Linux     kernel's graphics module. Incrementing the page pointer     for huge pages was not in sync with the reference     counter, and this could lead to an out-of-bounds access     or a denial of service. This flaw allows a local     attacker with special user privileges (or root) to     cause memory exploitation.(CVE-2019-19927)

    (CVE-2019-14615)

  - drivers/net/wireless/ath/ath10k/usb.c in the Linux kernel through 5.2.8 has a NULL pointer dereference via     an incomplete address in an endpoint descriptor. (CVE-2019-15099)

  - An issue was discovered in the Linux kernel through 5.2.9. There is 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.
    (CVE-2019-15291)

  - drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer dereference. NOTE: The security community disputes this issues as     not being serious enough to be deserving a CVE id (CVE-2019-16229)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16232)

  - An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. 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. (CVE-2019-18683)

  - In the Linux kernel through 5.3.8, f->fmt.sdr.reserved is uninitialized in rcar_drif_g_fmt_sdr_cap in     drivers/media/platform/rcar_drif.c, which could cause a memory disclosure problem. (CVE-2019-18786)

  - A memory leak in the sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     sof_get_ctrl_copy_params() failures, aka CID-45c1380358b1. (CVE-2019-18811)

  - A memory leak in the crypto_reportstat() function in crypto/crypto_user_stat.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     crypto_reportstat_alg() failures, aka CID-c03b04dcdba1. (CVE-2019-19050)

  - Two memory leaks in the mwifiex_pcie_init_evt_ring() function in     drivers/net/wireless/marvell/mwifiex/pcie.c in the Linux kernel through 5.3.11 allow attackers to cause a     denial of service (memory consumption) by triggering mwifiex_map_pci_memory() failures, aka     CID-d10dcb615c8e. (CVE-2019-19057)

  - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)

  - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the     Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka     CID-3f9361695113. (CVE-2019-19063)

  - A memory leak in the rsi_send_beacon() function in drivers/net/wireless/rsi/rsi_91x_mgmt.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     rsi_prepare_beacon() failures, aka CID-d563131ef23c. (CVE-2019-19071)

  - A memory leak in the bnxt_re_create_srq() function in drivers/infiniband/hw/bnxt_re/ib_verbs.c in the     Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by     triggering copy to udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)

  - A memory leak in the ath10k_usb_hif_tx_sg() function in drivers/net/wireless/ath/ath10k/usb.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     usb_submit_urb() failures, aka CID-b8d17e7d93d2. (CVE-2019-19078)

  - Memory leaks in *create_resource_pool() functions under drivers/gpu/drm/amd/display/dc in the Linux kernel     through 5.3.11 allow attackers to cause a denial of service (memory consumption). This affects the     dce120_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c, the     dce110_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c, the     dce100_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c, the     dcn10_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c, and the     dce112_create_resource_pool() function in drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c, aka     CID-104c307147ad. (CVE-2019-19082)

  - In the Linux kernel before 5.4.2, the io_uring feature leads to requests that inadvertently have UID 0 and     full capabilities, aka CID-181e448d8709. This is related to fs/io-wq.c, fs/io_uring.c, and net/socket.c.
    For example, an attacker can bypass intended restrictions on adding an IPv4 address to the loopback     interface. This occurs because IORING_OP_SENDMSG operations, although requested in the context of an     unprivileged user, are sometimes performed by a kernel worker thread without considering that context.
    (CVE-2019-19241)

  - vcs_write in drivers/tty/vt/vc_screen.c in the Linux kernel through 5.3.13 does not prevent write access     to vcsu devices, aka CID-0c9acb1af77a. (CVE-2019-19252)

  - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way     the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID     features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use     this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)

  - fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is     used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have     unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling     of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.
    (CVE-2019-19602)

  - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors     in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka     CID-4ea99936a163. (CVE-2019-19767)

  - In the Linux kernel through 5.4.6, there are information leaks of uninitialized memory to a USB device in     the drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c driver, aka CID-da2311a6385c. (CVE-2019-19947)

  - In the Linux kernel through 5.4.6, there is a NULL pointer dereference in     drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related     to a PHY down race condition, aka CID-f70267f379b5. (CVE-2019-19965)

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