a denial of service (system crash). (CVE-2019-15218)

It was discovered that the Line 6 POD USB device driver in the Linux
kernel did not properly validate data size information from the
device. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2019-15221)

Muyu Yu discovered that the CAN implementation in the Linux kernel in
some situations did not properly restrict the field size when
processing outgoing frames. A local attacker with CAP_NET_ADMIN
privileges could use this to execute arbitrary code. (CVE-2019-3701)

Vladis Dronov discovered that the debug interface for the Linux
kernel's HID subsystem did not properly validate passed parameters in
some situations. A local privileged attacker could use this to cause a
denial of service (infinite loop). (CVE-2019-3819).

It is not clear how this might be exploited. - CVE-2019-1125 It was discovered that most x86 processors could speculatively skip a conditional SWAPGS instruction used when entering the kernel from user mode, and/or could speculatively execute it when it should be skipped. This is a subtype of Spectre variant 1, which could allow local users to obtain sensitive information from the kernel or other processes. It has been mitigated by using memory barriers to limit speculative execution.

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

  - CVE-2018-20836
    chenxiang reported a race condition in libsas, the
    kernel subsystem supporting Serial Attached SCSI (SAS)
    devices, which could lead to a use-after-free. It is not
    clear how this might be exploited.

  - CVE-2019-1125
    It was discovered that most x86 processors could
    speculatively skip a conditional SWAPGS instruction used
    when entering the kernel from user mode, and/or could
    speculatively execute it when it should be skipped. This
    is a subtype of Spectre variant 1, which could allow
    local users to obtain sensitive information from the
    kernel or other processes. It has been mitigated by
    using memory barriers to limit speculative execution.
    Systems using an i386 kernel are not affected as the
    kernel does not use SWAPGS.

  - CVE-2019-1999
    A race condition was discovered in the Android binder
    driver, which could lead to a use-after-free. If this
    driver is loaded, a local user might be able to use this
    for denial-of-service (memory corruption) or for
    privilege escalation.

  - CVE-2019-10207
    The syzkaller tool found a potential null dereference in
    various drivers for UART-attached Bluetooth adapters. A
    local user with access to a pty device or other suitable
    tty device could use this for denial-of-service
    (BUG/oops).

  - CVE-2019-10638
    Amit Klein and Benny Pinkas discovered that the
    generation of IP packet IDs used a weak hash function,
    'jhash'. This could enable tracking individual computers
    as they communicate with different remote servers and
    from different networks. The 'siphash' function is now
    used instead.

  - CVE-2019-12817
    It was discovered that on the PowerPC (ppc64el)
    architecture, the hash page table (HPT) code did not
    correctly handle fork() in a process with memory mapped
    at addresses above 512 TiB. This could lead to a
    use-after-free in the kernel, or unintended sharing of
    memory between user processes. A local user could use
    this for privilege escalation. Systems using the radix
    MMU, or a custom kernel with a 4 KiB page size, are not
    affected.

  - CVE-2019-12984
    It was discovered that the NFC protocol implementation
    did not properly validate a netlink control message,
    potentially leading to a NULL pointer dereference. A
    local user on a system with an NFC interface could use
    this for denial-of-service (BUG/oops).

  - CVE-2019-13233
    Jann Horn discovered a race condition on the x86
    architecture, in use of the LDT. This could lead to a
    use-after-free. A local user could possibly use this for
    denial-of-service.

  - CVE-2019-13631
    It was discovered that the gtco driver for USB input
    tablets could overrun a stack buffer with constant data
    while parsing the device's descriptor. A physically
    present user with a specially constructed USB device
    could use this to cause a denial-of-service (BUG/oops),
    or possibly for privilege escalation.

  - CVE-2019-13648
    Praveen Pandey reported that on PowerPC (ppc64el)
    systems without Transactional Memory (TM), the kernel
    would still attempt to restore TM state passed to the
    sigreturn() system call. A local user could use this for
    denial-of-service (oops).

  - CVE-2019-14283
    The syzkaller tool found a missing bounds check in the
    floppy disk driver. A local user with access to a floppy
    disk device, with a disk present, could use this to read
    kernel memory beyond the I/O buffer, possibly obtaining
    sensitive information.

  - CVE-2019-14284
    The syzkaller tool found a potential division-by-zero in
    the floppy disk driver. A local user with access to a
    floppy disk device could use this for denial-of-service
    (oops)."

"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 flaw was found in the
    Linux kernel's NFS implementation, all versions 3.x and
    all versions 4.x up to 4.20. 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)An issue was
    discovered in the Linux kernel before 4.18.7. In
    create_qp_common in drivers/infiniband/hw/mlx5/qp.c,
    mlx5_ib_create_qp_resp was never initialized, resulting
    in a leak of stack memory to
    userspace.(CVE-2018-20855)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)The
    Linux kernel 4.x (starting from 4.1) and 5.x before
    5.0.8 allows Information Exposure (partial kernel
    address disclosure), leading to a KASLR bypass.
    Specifically, it is possible to extract the KASLR
    kernel image offset using the IP ID values the kernel
    produces for connection-less protocols (e.g., UDP and
    ICMP). When such traffic is sent to multiple
    destination IP addresses, it is possible to obtain hash
    collisions (of indices to the counter array) and
    thereby obtain the hashing key (via enumeration). This
    key contains enough bits from a kernel address (of a
    static variable) so when the key is extracted (via
    enumeration), the offset of the kernel image is
    exposed. This attack can be carried out remotely, by
    the attacker forcing the target device to send UDP or
    ICMP (or certain other) traffic to attacker-controlled
    IP addresses. Forcing a server to send UDP traffic is
    trivial if the server is a DNS server. ICMP traffic is
    trivial if the server answers ICMP Echo requests
    (ping). For client targets, if the target visits the
    attacker's web page, then WebRTC or gQUIC can be used
    to force UDP traffic to attacker-controlled IP
    addresses. NOTE: this attack against KASLR became
    viable in 4.1 because IP ID generation was changed to
    have a dependency on an address associated with a
    network namespace.(CVE-2019-10639)** DISPUTED ** 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)**DISPUTED** An issue was
    discovered in the efi subsystem in the Linux kernel
    through 5.1.5. phys_efi_set_virtual_address_map in
    arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
    arch/x86/platform/efi/efi_64.c mishandle memory
    allocation failures. NOTE: This id is disputed as not
    being an issue because ?All the code touched by the
    referenced commit runs only at boot, before any user
    processes are started. Therefore, there is no
    possibility for an unprivileged user to control
    it.?.(CVE-2019-12380)** DISPUTED ** 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)** DISPUTED ** An issue was
    discovered in the MPT3COMMAND case in _ctl_ioctl_main
    in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux
    kernel through 5.1.5. It allows local users to cause a
    denial of service or possibly have unspecified other
    impact by changing the value of ioc_number between two
    kernel reads of that value, aka a 'double fetch'
    vulnerability. NOTE: a third party reports that this is
    unexploitable because the doubly fetched value is not
    used.(CVE-2019-12456)An issue was discovered in the
    Linux kernel before 4.20.15. The nfc_llcp_build_tlv
    function in net/nfc/llcp_commands.c may return NULL. If
    the caller does not check for this, it will trigger a
    NULL pointer dereference. This will cause denial of
    service. This affects nfc_llcp_build_gb in
    net/nfc/llcp_core.c.(CVE-2019-12818)An issue was
    discovered in the Linux kernel before 5.0. The function
    __mdiobus_register() in drivers/net/phy/mdio_bus.c
    calls put_device(), which will trigger a
    fixed_mdio_bus_init use-after-free. This will cause a
    denial of service.(CVE-2019-12819)A NULL pointer
    dereference vulnerability in the function
    nfc_genl_deactivate_target() in net/nfc/netlink.c in
    the Linux kernel before 5.1.13 can be triggered by a
    malicious user-mode program that omits certain NFC
    attributes, leading to denial of
    service.(CVE-2019-12984)In the Linux kernel before
    5.1.17, ptrace_link in kernel/ptrace.c mishandles the
    recording of the credentials of a process that wants to
    create a ptrace relationship, which allows local users
    to obtain root access by leveraging certain scenarios
    with a parent-child process relationship, where a
    parent drops privileges and calls execve (potentially
    allowing control by an attacker). One contributing
    factor is an object lifetime issue (which can also
    cause a panic). Another contributing factor is
    incorrect marking of a ptrace relationship as
    privileged, which is exploitable through (for example)
    Polkit's pkexec helper with PTRACE_TRACEME. NOTE:
    SELinux deny_ptrace might be a usable workaround in
    some environments.(CVE-2019-13272)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)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 the
    Linux kernel before 5.2.3, set_geometry in
    drivers/block/floppy.c does not validate the sect and
    head fields, as demonstrated by an integer overflow and
    out-of-bounds read. It can be triggered by an
    unprivileged local user when a floppy disk has been
    inserted. NOTE: QEMU creates the floppy device by
    default.(CVE-2019-14283)In the Linux kernel before
    5.2.3, drivers/block/floppy.c allows a denial of
    service by setup_format_params division-by-zero. Two
    consecutive ioctls can trigger the bug: the first one
    should set the drive geometry with .sect and .rate
    values that make F_SECT_PER_TRACK be zero. Next, the
    floppy format operation should be called. It can be
    triggered by an unprivileged local user even when a
    floppy disk has not been inserted. NOTE: QEMU creates
    the floppy device by default.(CVE-2019-14284)In the
    Linux kernel before 4.16.4, a double-locking error in
    drivers/usb/dwc3/gadget.c may potentially cause a
    deadlock with f_hid.(CVE-2019-14763)An issue was
    discovered in the Linux kernel before 5.2.6. There is a
    use-after-free caused by a malicious USB device in the
    drivers/media/v4l2-core/v4l2-dev.c driver because
    drivers/media/radio/radio-raremono.c does not properly
    allocate memory.(CVE-2019-15211)An issue was discovered
    in the Linux kernel before 5.0.9. There is a
    use-after-free in atalk_proc_exit, related to
    net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and
    net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)Note:
    kernel-4.19.36-vhulk1907.1.0.h529 and earlier versions
    in EulerOS Virtualization for ARM 64 3.0.2.0 return
    incorrect time information when executing the uname -a
    command.
