DATE CVE VULNERABILITY TITLE RISK
2009-08-14 CVE-2009-2768 NULL Pointer Dereference vulnerability in Linux Kernel
The load_flat_shared_library function in fs/binfmt_flat.c in the flat subsystem in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by executing a shared flat binary, which triggers an access of an "uninitialized cred pointer."

2009-08-14 CVE-2009-2692 Use of Uninitialized Resource vulnerability in multiple products
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.

2008-07-09 CVE-2008-2931 Improper Privilege Management vulnerability in multiple products
The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.

2008-07-09 CVE-2008-2812 NULL Pointer Dereference vulnerability in multiple products
The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.
7.8
2006-10-10 CVE-2006-4997 Use After Free vulnerability in multiple products
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).

2006-10-05 CVE-2006-5158 Improper Locking vulnerability in multiple products
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.

2005-09-06 CVE-2005-2801 Incorrect Comparison vulnerability in Linux Kernel 2.6.0
xattr.c in the ext2 and ext3 file system code for Linux kernel 2.6 does not properly compare the name_index fields when sharing xattr blocks, which could prevent default ACLs from being applied.

2004-12-31 CVE-2004-2013 Integer Overflow or Wraparound vulnerability in Linux Kernel
Integer overflow in the SCTP_SOCKOPT_DEBUG_NAME SCTP socket option in socket.c in the Linux kernel 2.4.25 and earlier allows local users to execute arbitrary code via an optlen value of -1, which causes kmalloc to allocate 0 bytes of memory.

2004-12-23 CVE-2004-0816 Integer Underflow (Wrap or Wraparound) vulnerability in Linux Kernel
Integer underflow in the firewall logging rules for iptables in Linux before 2.6.8 allows remote attackers to cause a denial of service (application crash) via a malformed IP packet.
