"It was discovered that the direct-IO subsystem did not correctly
validate certain structures. A local attacker could exploit this to
cause a system crash, leading to a denial of service. (CVE-2007-6716)

It was discovered that the disabling of the ZERO_PAGE optimization
could lead to large memory consumption. A local attacker could exploit
this to allocate all available memory, leading to a denial of service.
(CVE-2008-2372)

It was discovered that the Datagram Congestion Control Protocol (DCCP)
did not correctly validate its arguments. If DCCP was in use, a remote
attacker could send specially crafted network traffic and cause a
system crash, leading to a denial of service. (CVE-2008-3276)

It was discovered that the SBNI WAN driver did not correctly check for
the NET_ADMIN capability. A malicious local root user lacking
CAP_NET_ADMIN would be able to change the WAN device configuration,
leading to a denial of service. (CVE-2008-3525)

It was discovered that the Stream Control Transmission Protocol (SCTP)
did not correctly validate the key length in the SCTP_AUTH_KEY option.
If SCTP is in use, a remote attacker could send specially crafted
network traffic that would crash the system, leading to a denial of
service. (CVE-2008-3526)

It was discovered that the tmpfs implementation did not correctly
handle certain sequences of inode operations. A local attacker could
exploit this to crash the system, leading to a denial of service.
(CVE-2008-3534)

It was discovered that the readv/writev functions did not correctly
handle certain sequences of file operations. A local attacker could
exploit this to crash the system, leading to a denial of service.
(CVE-2008-3535)

It was discovered that SCTP did not correctly validate its userspace
arguments. A local attacker could call certain sctp_* functions with
malicious options and cause a system crash, leading to a denial of
service. (CVE-2008-3792, CVE-2008-4113, CVE-2008-4445)

It was discovered the the i915 video driver did not correctly validate
memory addresses. A local attacker could exploit this to remap memory
that could cause a system crash, leading to a denial of service.
(CVE-2008-3831)

Johann Dahm and David Richter discovered that NFSv4 did not correctly
handle certain file ACLs. If NFSv4 is in use, a local attacker could
create a malicious ACL that could cause a system crash, leading to a
denial of service. (CVE-2008-3915).

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service or leak sensitive data. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-2008-3272
    Tobias Klein reported a locally exploitable data leak in
    the snd_seq_oss_synth_make_info() function. This may
    allow local users to gain access to sensitive
    information.

  - CVE-2008-3275
    Zoltan Sogor discovered a coding error in the VFS that
    allows local users to exploit a kernel memory leak
    resulting in a denial of service.

  - CVE-2008-3276
    Eugene Teo reported an integer overflow in the DCCP
    subsystem that may allow remote attackers to cause a
    denial of service in the form of a kernel panic.

  - CVE-2008-3526
    Eugene Teo reported a missing bounds check in the SCTP
    subsystem. By exploiting an integer overflow in the
    SCTP_AUTH_KEY handling code, remote attackers may be
    able to cause a denial of service in the form of a
    kernel panic.

  - CVE-2008-3534
    Kel Modderman reported an issue in the tmpfs filesystem
    that allows local users to crash a system by triggering
    a kernel BUG() assertion.

  - CVE-2008-3535
    Alexey Dobriyan discovered an off-by-one-error in the
    iov_iter_advance function which can be exploited by
    local users to crash a system, resulting in a denial of
    service.

  - CVE-2008-3792
    Vlad Yasevich reported several NULL pointer reference
    conditions in the SCTP subsystem that can be triggered
    by entering sctp-auth codepaths when the AUTH feature is
    inactive. This may allow attackers to cause a denial of
    service condition via a system panic.

  - CVE-2008-3915
    Johann Dahm and David Richter reported an issue in the
    nfsd subsystem that may allow remote attackers to cause
    a denial of service via a buffer overflow."
