DATE CVE VULNERABILITY TITLE RISK
2012-02-02 CVE-2011-2525 NULL Pointer Dereference vulnerability in multiple products
The qdisc_notify function in net/sched/sch_api.c in the Linux kernel before 2.6.35 does not prevent tc_fill_qdisc function calls referencing builtin (aka CQ_F_BUILTIN) Qdisc structures, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted call.

linux redhat CWE-476
7.8
2011-10-10 CVE-2011-2189 Resource Exhaustion vulnerability in multiple products
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.

2011-09-06 CVE-2011-1771 NULL Pointer Dereference vulnerability in Linux Kernel
The cifs_close function in fs/cifs/file.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (NULL pointer dereference and BUG) or possibly have unspecified other impact by setting the O_DIRECT flag during an attempt to open a file on a CIFS filesystem.

2011-07-18 CVE-2010-4656 Out-of-bounds Write vulnerability in multiple products
The iowarrior_write function in drivers/usb/misc/iowarrior.c in the Linux kernel before 2.6.37 does not properly allocate memory, which might allow local users to trigger a heap-based buffer overflow, and consequently cause a denial of service or gain privileges, via a long report.

linux canonical CWE-787
7.8
2011-06-24 CVE-2011-1770 Integer Underflow (Wrap or Wraparound) vulnerability in multiple products
Integer underflow in the dccp_parse_options function (net/dccp/options.c) in the Linux kernel before 2.6.33.14 allows remote attackers to cause a denial of service via a Datagram Congestion Control Protocol (DCCP) packet with an invalid feature options length, which triggers a buffer over-read.

linux fedoraproject CWE-191
7.5
2011-06-22 CVE-2011-2534 Classic Buffer Overflow vulnerability in Linux Kernel
Buffer overflow in the clusterip_proc_write function in net/ipv4/netfilter/ipt_CLUSTERIP.c in the Linux kernel before 2.6.39 might allow local users to cause a denial of service or have unspecified other impact via a crafted write operation, related to string data that lacks a terminating '\0' character.

low complexity
linux CWE-120
7.8
2011-05-26 CVE-2010-4805 Resource Exhaustion vulnerability in multiple products
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.35 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service by sending a large amount of network traffic, related to the sk_add_backlog function and the sk_rmem_alloc socket field.

linux redhat CWE-400
7.5
2011-05-26 CVE-2010-4251 Resource Exhaustion vulnerability in multiple products
The socket implementation in net/core/sock.c in the Linux kernel before 2.6.34 does not properly manage a backlog of received packets, which allows remote attackers to cause a denial of service (memory consumption) by sending a large amount of network traffic, as demonstrated by netperf UDP tests.

2011-02-18 CVE-2011-0709 NULL Pointer Dereference vulnerability in Linux Kernel
The br_mdb_ip_get function in net/bridge/br_multicast.c in the Linux kernel before 2.6.35-rc5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an IGMP packet, related to lack of a multicast table.

linux CWE-476
7.5
2010-12-06 CVE-2010-3904 Improper Validation of Specified Quantity in Input vulnerability in multiple products
The rds_page_copy_user function in net/rds/page.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel before 2.6.36 does not properly validate addresses obtained from user space, which allows local users to gain privileges via crafted use of the sendmsg and recvmsg system calls.
