DATE CVE VULNERABILITY TITLE RISK
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/.

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.

2005-11-27 CVE-2005-3847 Improper Locking vulnerability in multiple products
The handle_stop_signal function in signal.c in Linux kernel 2.6.11 up to other versions before 2.6.13 and 2.6.12.6 allows local users to cause a denial of service (deadlock) by sending a SIGKILL to a real-time threaded process while it is performing a core dump.

5.5
2005-10-21 CVE-2005-3274 NULL Pointer Dereference vulnerability in multiple products
Race condition in ip_vs_conn_flush in Linux 2.6 before 2.6.13 and 2.4 before 2.4.32-pre2, when running on SMP systems, allows local users to cause a denial of service (null dereference) by causing a connection timer to expire while the connection table is being flushed before the appropriate lock is acquired.

linux debian CWE-476
4.7
2005-09-30 CVE-2005-3106 Improper Locking vulnerability in multiple products
Race condition in Linux 2.6, when threads are sharing memory mapping via CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a denial of service (deadlock) by triggering a core dump while waiting for a thread that has just performed an exec.

4.7
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.

linux CWE-697
7.5
2005-08-04 CVE-2005-2456 Improper Locking vulnerability in multiple products
Array index overflow in the xfrm_sk_policy_insert function in xfrm_user.c in Linux kernel 2.6 allows local users to cause a denial of service (oops or deadlock) and possibly execute arbitrary code via a p->dir value that is larger than XFRM_POLICY_OUT, which is used as an index in the sock->sk_policy array.

5.5
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.

7.8
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.
