nf_conntrack in netfilter in the Linux kernel before 2.6.20.3 does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments.

The ipv6_getsockopt_sticky function in net/ipv6/ipv6_sockglue.c in the Linux kernel before 2.6.20.2 allows local users to read arbitrary kernel memory via certain getsockopt calls that trigger a NULL dereference.

The do_ipv6_setsockopt function in net/ipv6/ipv6_sockglue.c in Linux kernel before 2.6.20, and possibly other versions, allows local users to cause a denial of service (oops) by calling setsockopt with the IPV6_RTHDR option name and possibly a zero option length or invalid option value, which triggers a NULL pointer dereference.

Multiple buffer overflows in the (1) read and (2) write handlers in the Omnikey CardMan 4040 driver in the Linux kernel before 2.6.21-rc3 allow local users to gain privileges.

The Linux kernel 2.6.13 and other versions before 2.6.20.1 allows remote attackers to cause a denial of service (oops) via a crafted NFSACL 2 ACCESS request that triggers a free of an incorrect pointer.

The key serial number collision avoidance code in the key_alloc_serial function in Linux kernel 2.6.9 up to 2.6.20 allows local users to cause a denial of service (crash) via vectors that trigger a null dereference, as originally reported as "spinlock CPU recursion."

Linux kernel before 2.6.18, when running on x86_64 systems, does not properly save or restore EFLAGS during a context switch, which allows local users to cause a denial of service (crash) by causing SYSENTER to set an NT flag, which can trigger a crash on the IRET of the next task.

ip6_tables in netfilter in the Linux kernel before 2.6.16.31 allows remote attackers to (1) bypass a rule that disallows a protocol, via a packet with the protocol header not located immediately after the fragment header, aka "ip6_tables protocol bypass bug;" and (2) bypass a rule that looks for a certain extension header, via a packet with an extension header outside the first fragment, aka "ip6_tables extension header bypass bug."

Linux kernel does not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which allows local users to cause a denial of service (process crash), as demonstrated using a process that sets the Alignment Check flag (EFLAGS 0x40000), which triggers a SIGBUS in other processes that have an unaligned access.

The clip_mkip function in net/atm/clip.c of the ATM subsystem in Linux kernel allows remote attackers to cause a denial of service (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (freed pointer dereference).

The nlmclnt_mark_reclaim in clntlock.c in NFS lockd in Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops (null dereference) and a deadlock.

Unspecified vulnerability in the sctp_make_abort_user function in the SCTP implementation in Linux 2.6.x before 2.6.17.10 and 2.4.23 up to 2.4.33 allows local users to cause a denial of service (panic) and possibly gain root privileges via unknown attack vectors.

Linux kernel 2.x.6 before 2.6.17.9 and 2.4.x before 2.4.33.1 on PowerPC PPC970 systems allows local users to cause a denial of service (crash) related to the "HID0 attention enable on PPC970 at boot time."

The Universal Disk Format (UDF) filesystem driver in Linux kernel 2.6.17 and earlier allows local users to cause a denial of service (hang and crash) via certain operations involving truncated files, as demonstrated via the dd command.

The dvd_read_bca function in the DVD handling code in drivers/cdrom/cdrom.c in Linux kernel 2.2.16, and later versions, assigns the wrong value to a length variable, which allows local users to execute arbitrary code via a crafted USB Storage device that triggers a buffer overflow.

artswrapper in aRts, when running setuid root on Linux 2.6.0 or later versions, does not check the return value of the setuid function call, which allows local users to gain root privileges by causing setuid to fail, which prevents artsd from dropping privileges.

Directory traversal vulnerability in CIFS in Linux 2.6.16 and earlier allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences, a similar vulnerability to CVE-2006-1864.

The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the state of floating point instructions of other processes, which can be leveraged to obtain sensitive information such as cryptographic keys. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels.

sys_mbind in mempolicy.c in Linux kernel 2.6.16 and earlier does not sanity check the maxnod variable before making certain computations for the get_nodes function, which has unknown impact and attack vectors.

Buffer overflow in the MoxaDriverIoctl function for the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x before 2.6.22 allows local users to execute arbitrary code via a certain modified length value.
