  - CVE-2016-2188: The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel allowed     physically proximate attackers to cause a denial of     service (NULL pointer dereference and system crash) via     a crafted endpoints value in a USB device descriptor     (bnc#970956).

  - CVE-2016-2847: fs/pipe.c in the Linux kernel did not     limit the amount of unread data in pipes, which allowed     local users to cause a denial of service (memory     consumption) by creating many pipes with non-default     sizes (bsc#970948).

  - CVE-2016-3134: The netfilter subsystem in the Linux     kernel did not validate certain offset fields, which     allowed local users to gain privileges or cause a denial     of service (heap memory corruption) via an     IPT_SO_SET_REPLACE setsockopt call (bnc#971126 971793).

  - CVE-2016-3136: The mct_u232_msr_to_state function in     drivers/usb/serial/mct_u232.c in the Linux kernel     allowed physically proximate attackers to cause a denial     of service (NULL pointer dereference and system crash)     via a crafted USB device without two interrupt-in     endpoint descriptors (bnc#970955).

  - CVE-2016-3137: drivers/usb/serial/cypress_m8.c in the     Linux kernel allowed physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a USB device without both an     interrupt-in and an interrupt-out endpoint descriptor,     related to the cypress_generic_port_probe and     cypress_open functions (bnc#970970).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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

  - CVE-2015-7515, CVE-2016-2184, CVE-2016-2185,     CVE-2016-2186, CVE-2016-2187, CVE-2016-3136,     CVE-2016-3137, CVE-2016-3138, CVE-2016-3140     Ralf Spenneberg of OpenSource Security reported that     various USB drivers do not sufficiently validate USB     descriptors. This allowed a physically present user with     a specially designed USB device to cause a denial of     service (crash).

  - CVE-2016-0821     Solar Designer noted that the list 'poisoning' feature,     intended to mitigate the effects of bugs in list     manipulation in the kernel, used poison values within     the range of virtual addresses that can be allocated by     user processes.

  - CVE-2016-1237     David Sinquin discovered that nfsd does not check     permissions when setting ACLs, allowing users to grant     themselves permissions to a file by setting the ACL.

  - CVE-2016-1583     Jann Horn of Google Project Zero reported that the     eCryptfs filesystem could be used together with the proc     filesystem to cause a kernel stack overflow. If the     ecryptfs-utils package is installed, local users could     exploit this, via the mount.ecryptfs_private program,     for denial of service (crash) or possibly for privilege     escalation.

  - CVE-2016-2117     Justin Yackoski of Cryptonite discovered that the     Atheros L2 ethernet driver incorrectly enables     scatter/gather I/O. A remote attacker could take     advantage of this flaw to obtain potentially sensitive     information from kernel memory.

  - CVE-2016-2143     Marcin Koscielnicki discovered that the fork     implementation in the Linux kernel on s390 platforms     mishandles the case of four page-table levels, which     allows local users to cause a denial of service (system     crash).

  - CVE-2016-3070     Jan Stancek of Red Hat discovered a local denial of     service vulnerability in AIO handling.

  - CVE-2016-3134     The Google Project Zero team found that the netfilter     subsystem does not sufficiently validate filter table     entries. A user with the CAP_NET_ADMIN capability could     use this for denial of service (crash) or possibly for     privilege escalation. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this allows     privilege escalation.

  - CVE-2016-3156     Solar Designer discovered that the IPv4 implementation     in the Linux kernel did not perform the destruction of     inet device objects properly. An attacker in a guest OS     could use this to cause a denial of service (networking     outage) in the host OS.

  - CVE-2016-3157 / XSA-171     Andy Lutomirski discovered that the x86_64 (amd64) task     switching implementation did not correctly update the     I/O permission level when running as a Xen paravirtual     (PV) guest. In some configurations this would allow     local users to cause a denial of service (crash) or to     escalate their privileges within the guest.

  - CVE-2016-3672     Hector Marco and Ismael Ripoll noted that it was     possible to disable Address Space Layout Randomisation     (ASLR) for x86_32 (i386) programs by removing the stack     resource limit. This made it easier for local users to     exploit security flaws in programs that have the setuid     or setgid flag set.

  - CVE-2016-3951     It was discovered that the cdc_ncm driver would free     memory prematurely if certain errors occurred during its     initialisation. This allowed a physically present user     with a specially designed USB device to cause a denial     of service (crash) or possibly to escalate their     privileges.

  - CVE-2016-3955     Ignat Korchagin reported that the usbip subsystem did     not check the length of data received for a USB buffer.
    This allowed denial of service (crash) or privilege     escalation on a system configured as a usbip client, by     the usbip server or by an attacker able to impersonate     it over the network. A system configured as a usbip     server might be similarly vulnerable to physically     present users.

  - CVE-2016-3961 / XSA-174     Vitaly Kuznetsov of Red Hat discovered that Linux     allowed the use of hugetlbfs on x86 (i386 and amd64)     systems even when running as a Xen paravirtualised (PV)     guest, although Xen does not support huge pages. This     allowed users with access to /dev/hugepages to cause a     denial of service (crash) in the guest.

  - CVE-2016-4470     David Howells of Red Hat discovered that a local user     can trigger a flaw in the Linux kernel's handling of key     lookups in the keychain subsystem, leading to a denial     of service (crash) or possibly to privilege escalation.

  - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486,     CVE-2016-4569, CVE-2016-4578, CVE-2016-4580,     CVE-2016-5243, CVE-2016-5244

    Kangjie Lu reported that the USB devio, llc, rtnetlink,     ALSA timer, x25, tipc, and rds facilities leaked     information from the kernel stack.

  - CVE-2016-4565     Jann Horn of Google Project Zero reported that various     components in the InfiniBand stack implemented unusual     semantics for the write() operation. On a system with     InfiniBand drivers loaded, local users could use this     for denial of service or privilege escalation.

  - CVE-2016-4581     Tycho Andersen discovered that in some situations the     Linux kernel did not handle propagated mounts correctly.
    A local user can take advantage of this flaw to cause a     denial of service (system crash).

  - CVE-2016-4805     Baozeng Ding discovered a use-after-free in the generic     PPP layer in the Linux kernel. A local user can take     advantage of this flaw to cause a denial of service     (system crash), or potentially escalate their     privileges.

  - CVE-2016-4913     Al Viro found that the ISO9660 filesystem implementation     did not correctly count the length of certain invalid     name entries. Reading a directory containing such name     entries would leak information from kernel memory. Users     permitted to mount disks or disk images could use this     to obtain sensitive information.

  - CVE-2016-4997 / CVE-2016-4998     Jesse Hertz and Tim Newsham discovered that missing     input sanitising in Netfilter socket handling may result     in denial of service. Debian disables unprivileged user     namespaces by default, if locally enabled with the     kernel.unprivileged_userns_clone sysctl, this also     allows privilege escalation.
