NFS did not correctly handle races between fcntl and interrupts. A local
attacker on an NFS mount could consume unlimited kernel memory, leading to
a denial of service. (CVE-2008-4307)

Sparc syscalls did not correctly check mmap regions. A local attacker could
cause a system panic, leading to a denial of service. (CVE-2008-6107)

In certain situations, cloned processes were able to send signals to parent
processes, crossing privilege boundaries. A local attacker could send
arbitrary signals to parent processes, leading to a denial of service.

The 64-bit syscall interfaces did not correctly handle sign extension. A
local attacker could make malicious syscalls, possibly gaining root
privileges. The x86_64 architecture was not affected. (CVE-2009-0029)

The SCTP stack did not correctly validate FORWARD-TSN packets. A remote
attacker could send specially crafted SCTP traffic causing a system crash,
leading to a denial of service. (CVE-2009-0065)

The Dell platform device did not correctly validate user parameters. A
local attacker could perform specially crafted reads to crash the system,
leading to a denial of service. (CVE-2009-0322)

Network interfaces statistics for the SysKonnect FDDI driver did not check
capabilities. A local user could reset statistics, potentially interfering
with packet accounting systems. (CVE-2009-0675)

The getsockopt function did not correctly clear certain parameters. A local
attacker could read leaked kernel memory, leading to a loss of privacy.

The syscall interface did not correctly validate parameters when crossing
the 64-bit/32-bit boundary. A local attacker could bypass certain syscall
restricts via crafted syscalls. (CVE-2009-0834, CVE-2009-0835)

The shared memory subsystem did not correctly handle certain shmctl calls
when CONFIG_SHMEM was disabled. Ubuntu kernels were not vulnerable, since
CONFIG_SHMEM is enabled by default. (CVE-2009-0859)
