CVE-2014-7826

kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application.

The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to fix various bugs and security issues.

The following security bugs have been fixed:

* 

  CVE-2014-1739: The media_device_enum_entities function in
  drivers/media/media-device.c in the Linux kernel before 3.14.6 does
  not initialize a certain data structure, which allows local users to
  obtain sensitive information from kernel memory by leveraging
  /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call
  (bnc#882804).

* 

  CVE-2014-4171: mm/shmem.c in the Linux kernel through 3.15.1 does not
  properly implement the interaction between range notification and
  hole punching, which allows local users to cause a denial of service
  (i_mutex hold) by using the mmap system call to access a hole, as
  demonstrated by interfering with intended shmem activity by blocking
  completion of (1) an MADV_REMOVE madvise call or (2) an
  FALLOC_FL_PUNCH_HOLE fallocate call (bnc#883518).

* 

  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-2014-4667: 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-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the
  Linux kernel through 3.15.6 allows local users to gain privileges by
  leveraging data-structure differences between an l2tp socket and an
  inet socket (bnc#887082).

* 

  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-2014-5471: Stack consumption vulnerability in the
  parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the
  Linux kernel through 3.16.1 allows local users to cause a denial of
  service (uncontrolled recursion, and system crash or reboot) via a
  crafted iso9660 image with a CL entry referring to a directory entry
  that has a CL entry. (bnc#892490)

* 

  CVE-2014-5472: The parse_rock_ridge_inode_internal function in
  fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users
  to cause a denial of service (unkillable mount process) via a crafted
  iso9660 image with a self-referential CL entry. (bnc#892490)

* 

  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-2014-4027: The rd_build_device_space function in
  drivers/target/target_core_rd.c in the Linux kernel before 3.14 does
  not properly initialize a certain data structure, which allows local
  users to obtain sensitive information from ramdisk_mcp memory by
  leveraging access to a SCSI initiator. (bnc#882639)

* 

  CVE-2014-3153 The futex_requeue function in kernel/futex.c in the
  Linux kernel through 3.14.5 does not ensure that…

The SUSE Linux Enterprise 11 Service Pack 2 kernel was updated to fix a regression introduced by the previous update:

* scsi_dh_alua: Incorrect reference counting in the SCSI ALUA
  initialization code lead to system crashes on boot (bnc#858831).

As the update introducing the regression was marked security, this is also marked security even though this bug is not security relevant.
