Summary

The klsi_105_get_line_state function in drivers/usb/serial/kl5kusb105.c in the Linux kernel before 4.9.5 places uninitialized heap-memory contents into a log entry upon a failure to read the line status, which allows local users to obtain sensitive information by reading the log.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Fuzzing and observing application log data/errors for application mapping
    An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. Fuzzing techniques involve sending random or malformed messages to a target and monitoring the target's response. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash. By observing logs and error messages, the attacker can learn details about the configuration of the target application and might be able to cause the target to disclose sensitive information.

information leak.

CVE-2017-6001

Di Shen discovered a race condition between concurrent calls to the
performance events subsystem, allowing a local attacker to escalate
privileges. This flaw exists because of an incomplete fix of
CVE-2016-6786. This can be mitigated by disabling unprivileged use of
performance events: sysctl kernel.perf_event_paranoid=3

CVE-2017-6074

Andrey Konovalov discovered a use-after-free vulnerability in the DCCP
networking code, which could result in denial of service or local
privilege escalation. On systems that do not already have the dccp
module loaded, this can be mitigated by disabling it: echo >>
/etc/modprobe.d/disable-dccp.conf install dccp false

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.84-2.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.39-1+deb8u1 or earlier.

We recommend that you upgrade your linux packages.

    other impacts via a crafted USB device, related to
    drivers/usb/storage/uas-detect.h and
    drivers/usb/storage/uas.c.(CVE-2017-16530i1/4%0

  - The implementation of big key management in

  - Buffer overflow in the exitcode_proc_write function in

  - It was found that unsharing a mount namespace could
    allow a user to see data beneath their restricted
    namespace.(CVE-2014-9717i1/4%0

  - A divide-by-zero flaw was discovered in the Linux
    kernel built with KVM virtualization
    support(CONFIG_KVM). The flaw occurs in the KVM
    module's Programmable Interval Timer(PIT) emulation,
    when PIT counters for channel 1 or 2 are set to zero(0)
    and a privileged user inside the guest attempts to read
    these counters. A privileged guest user with access to
    PIT I/O ports could exploit this issue to crash the

  - drivers/hid/hid-sony.c in the Human Interface Device
    (HID) subsystem in the Linux kernel through 3.11, when
    CONFIG_HID_SONY is enabled, allows physically proximate
    attackers to cause a denial of service (heap-based

    kernel through 4.19.13. A local attacker can craft a
    malicious IOCTL function call to overwrite arbitrary
    kernel memory, resulting in a Denial of Service or
    privilege escalation.(CVE-2018-20669i1/4%0

  - It was found that the permission checks performed by
    the Linux kernel when a netlink message was received
    were not sufficient. A local, unprivileged user could
    potentially bypass these restrictions by passing a
    netlink socket as stdout or stderr to a more privileged
    process and altering the output of this
    process.(CVE-2014-0181i1/4%0

  - An issue was discovered in the XFS filesystem in
    fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A
    NULL pointer dereference may occur for a corrupted xfs
    image after xfs_da_shrink_inode() is called with a NULL
    bp. This can lead to a system crash and a denial of
    service.(CVE-2018-13094i1/4%0

  - The irda_setsockopt function in net/irda/af_irda.c in
    the Linux kernel, through 4.16, allows local users to
    cause a denial of service (due to a use-after-free of
    the ias_object and a system crash) or possibly have
    unspecified other impact by leveraging an AF_IRDA
    socket.(CVE-2018-6555i1/4%0

  - The x86/fpu (Floating Point Unit) subsystem in the
    Linux kernel, when a processor supports the xsave
    feature but not the xsaves feature, does not correctly
    handle attempts to set reserved bits in the xstate
    header via the ptrace() or rt_sigreturn() system call.
    This allows local users to read the FPU registers of
    other processes on the system, related to
    arch/x86/kernel/fpu/regset.c and
    arch/x86/kernel/fpu/signal.c.(CVE-2017-15537i1/4%0

  - The fst_get_iface function in drivers/net/wan/farsync.c
    in the Linux kernel before 3.11.7 does not properly
    initialize a certain data structure, which allows local
    users to obtain sensitive information from kernel
    memory by leveraging the CAP_NET_ADMIN capability for
    an SIOCWANDEV ioctl call.(CVE-2014-1444i1/4%0

  - In the Linux kernel, through 4.15.4, the floppy driver
    reveals the addresses of kernel functions and global
    variables using printk calls within the function
    show_floppy in drivers/block/floppy.c. An attacker can
    read this information from dmesg and use the addresses
    to find the locations of kernel code and data and
    bypass kernel security protections such as
    KASLR.(CVE-2018-7273i1/4%0

  - A flaw in 'arch/arm64/kernel/sys.c' in the Linux kernel
    allows local users to bypass the 'strict page
    permissions' protection mechanism and modify the
    system-call table and, consequently, gain privileges by
    leveraging write access.(CVE-2015-8967i1/4%0

  - The Linux kernel before 3.11 on ARM platforms, as used
    in Android before 2016-08-05 on Nexus 5 and 7 (2013)
    devices, does not properly consider user-space access
    to the TPIDRURW register, which allows local users to
    gain privileges via a crafted application, aka Android
    internal bug 28749743 and Qualcomm internal bug
    CR561044.(CVE-2014-9870i1/4%0

  - A NULL pointer dereference security flaw was found in
    the Linux kernel in the vcpu_scan_ioapic() function in
    arch/x86/kvm/x86.c. This allows local users with
    certain privileges to cause a denial of service via a
    crafted system call to the KVM
    subsystem.(CVE-2018-19407i1/4%0

  - It was found that current implementation of kl5kusb105
    driver failed to detect short transfers when attempting
    to read the line state and logged the content of the
    uninitialized heap transfer buffer.(CVE-2017-5549i1/4%0

    copying color maps to userspace, causing a heap buffer
    out-of-bounds read, leading to information disclosure.

    CAI Qian discovered that reference counting is not
    properly handled within proc_sys_readdir in the sysctl
    implementation, allowing a local denial of service
    (system hang) or possibly privilege escalation.

  - CVE-2017-2583

  - CVE-2017-5549
    It was discovered that the KLSI KL5KUSB105 serial USB
    device driver could log the contents of uninitialised
    kernel memory, resulting in an information leak.

  - CVE-2017-5551
    Jan Kara found that changing the POSIX ACL of a file on
    tmpfs never cleared its set-group-ID flag, which should
    be done if the user changing it is not a member of the
