  - CVE-2014-2706: Race condition in the mac80211 subsystem     in the Linux kernel before 3.13.7 allows remote     attackers to cause a denial of service (system crash)     via network traffic that improperly interacts with the     WLAN_STA_PS_STA state (aka power-save mode), related to     sta_info.c and tx.c. (bnc#871797)

  - CVE-2014-2851: Integer overflow in the ping_init_sock     function in net/ipv4/ping.c in the Linux kernel through     3.14.1 allows local users to cause a denial of service     (use-after-free and system crash) or possibly gain     privileges via a crafted application that leverages an     improperly managed reference counter. (bnc#873374)

  - CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2)     BPF_S_ANC_NLATTR_NEST extension implementations in the     sk_run_filter function in net/core/filter.c in the Linux     kernel through 3.14.3 do not check whether a certain     length value is sufficiently large, which allows local     users to cause a denial of service (integer underflow     and system crash) via crafted BPF instructions. NOTE:
    the affected code was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension     implementation in the sk_run_filter function in     net/core/filter.c in the Linux kernel through 3.14.3     uses the reverse order in a certain subtraction, which     allows local users to cause a denial of service     (over-read and system crash) via crafted BPF     instructions. NOTE: the affected code was moved to the
    __skb_get_nlattr_nest function before the vulnerability     was announced. (bnc#877257)

  - CVE-2014-3917: kernel/auditsc.c in the Linux kernel     through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with     certain syscall rules, allows local users to obtain     potentially sensitive single-bit values from kernel     memory or cause a denial of service (OOPS) via a large     value of a syscall number. (bnc#880484)

  - CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux     kernel through 3.15.1 on 32-bit x86 platforms, when     syscall auditing is enabled and the sep CPU feature flag     is set, allows local users to cause a denial of service     (OOPS and system crash) via an invalid syscall number,     as demonstrated by number 1000. (bnc#883724)

  - CVE-2014-4652: Race condition in the tlv handler     functionality in the snd_ctl_elem_user_tlv function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allows local users to     obtain sensitive information from kernel memory by     leveraging /dev/snd/controlCX access. (bnc#883795)

  - CVE-2014-4653: sound/core/control.c in the ALSA control     implementation in the Linux kernel before 3.15.2 does     not ensure possession of a read/write lock, which allows     local users to cause a denial of service     (use-after-free) and obtain sensitive information from     kernel memory by leveraging /dev/snd/controlCX access.
    (bnc#883795)

  - CVE-2014-4654: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not check     authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands,     which allows local users to remove kernel controls and     cause a denial of service (use-after-free and system     crash) by leveraging /dev/snd/controlCX access for an     ioctl call. (bnc#883795)

  - CVE-2014-4655: The snd_ctl_elem_add function in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 does not properly     maintain the user_ctl_count value, which allows local     users to cause a denial of service (integer overflow and     limit bypass) by leveraging /dev/snd/controlCX access     for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl     calls. (bnc#883795)

  - CVE-2014-4656: Multiple integer overflows in     sound/core/control.c in the ALSA control implementation     in the Linux kernel before 3.15.2 allow local users to     cause a denial of service by leveraging     /dev/snd/controlCX access, related to (1) index values     in the snd_ctl_add function and (2) numid values in the     snd_ctl_remove_numid_conflict function. (bnc#883795)

  - CVE-2014-4667: The sctp_association_free function in     net/sctp/associola.c in the Linux kernel before 3.15.2     does not properly manage a certain backlog value, which     allows remote attackers to cause a denial of service     (socket outage) via a crafted SCTP packet. (bnc#885422)

  - CVE-2014-4699: The Linux kernel before 3.15.4 on Intel     processors does not properly restrict use of a     non-canonical value for the saved RIP address in the     case of a system call that does not use IRET, which     allows local users to leverage a race condition and gain     privileges, or cause a denial of service (double fault),     via a crafted application that makes ptrace and fork     system calls. (bnc#885725)

  - CVE-2014-5077: The sctp_assoc_update function in     net/sctp/associola.c in the Linux kernel through 3.15.8,     when SCTP authentication is enabled, allows remote     attackers to cause a denial of service (NULL pointer     dereference and OOPS) by starting to establish an     association between two endpoints immediately after an     exchange of INIT and INIT ACK chunks to establish an     earlier association between these endpoints in the     opposite direction. (bnc#889173)

  - CVE-2013-4299: Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block device. (bnc#846404)
