DATE CVE VULNERABILITY TITLE RISK
2013-06-08 CVE-2011-4087 Improper Initialization vulnerability in Linux Kernel
The br_parse_ip_options function in net/bridge/br_netfilter.c in the Linux kernel before 2.6.39 does not properly initialize a certain data structure, which allows remote attackers to cause a denial of service by leveraging connectivity to a network interface that uses an Ethernet bridge device.

linux CWE-665
7.5
2013-06-08 CVE-2011-2482 NULL Pointer Dereference vulnerability in Linux Kernel
A certain Red Hat patch to the sctp_sock_migrate function in net/sctp/socket.c in the Linux kernel before 2.6.21, as used in Red Hat Enterprise Linux (RHEL) 5, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) via a crafted SCTP packet.

linux CWE-476
7.5
2013-06-08 CVE-2011-1180 Out-of-bounds Write vulnerability in Linux Kernel
Multiple stack-based buffer overflows in the iriap_getvaluebyclass_indication function in net/irda/iriap.c in the Linux kernel before 2.6.39 allow remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging connectivity to an IrDA infrared network and sending a large integer value for a (1) name length or (2) attribute length.

9.8
2013-06-07 CVE-2013-2147 Resource Management Errors vulnerability in Linux Kernel
The HP Smart Array controller disk-array driver and Compaq SMART2 controller disk-array driver in the Linux kernel through 3.9.4 do not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory via (1) a crafted IDAGETPCIINFO command for a /dev/ida device, related to the ida_locked_ioctl function in drivers/block/cpqarray.c or (2) a crafted CCISS_PASSTHRU32 command for a /dev/cciss device, related to the cciss_ioctl32_passthru function in drivers/block/cciss.c.

2.1
2013-06-07 CVE-2013-2128 Resource Exhaustion vulnerability in Linux Kernel
The tcp_read_sock function in net/ipv4/tcp.c in the Linux kernel before 2.6.34 does not properly manage skb consumption, which allows local users to cause a denial of service (system crash) via a crafted splice system call for a TCP socket.

linux CWE-400
5.5
2013-03-01 CVE-2011-2479 Resource Management Errors vulnerability in Linux Kernel
The Linux kernel before 2.6.39 does not properly create transparent huge pages in response to a MAP_PRIVATE mmap system call on /dev/zero, which allows local users to cause a denial of service (system crash) via a crafted application.
local
low complexity
linux CWE-399
5.5
2013-02-28 CVE-2013-0343 IPv6 Temporary Addresses Remote Security vulnerability in Linux Kernel
The ipv6_create_tempaddr function in net/ipv6/addrconf.c in the Linux kernel through 3.8 does not properly handle problems with the generation of IPv6 temporary addresses, which allows remote attackers to cause a denial of service (excessive retries and address-generation outage), and consequently obtain sensitive information, via ICMPv6 Router Advertisement (RA) messages.

3.2
2013-02-13 CVE-2013-0190 Improper Input Validation vulnerability in Linux Kernel
The xen_failsafe_callback function in Xen for the Linux kernel 2.6.23 and other versions, when running a 32-bit PVOPS guest, allows local users to cause a denial of service (guest crash) by triggering an iret fault, leading to use of an incorrect stack pointer and stack corruption.

linux CWE-20
4.9
2012-10-03 CVE-2012-3552 Race Condition vulnerability in multiple products
Race condition in the IP implementation in the Linux kernel before 3.0 might allow remote attackers to cause a denial of service (slab corruption and system crash) by sending packets to an application that sets socket options during the handling of network traffic.
network
high complexity
linux redhat CWE-362
5.9
2012-05-24 CVE-2011-4081 NULL Pointer Dereference vulnerability in Linux Kernel
crypto/ghash-generic.c in the Linux kernel before 3.1 allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact by triggering a failed or missing ghash_setkey function call, followed by a (1) ghash_update function call or (2) ghash_final function call, as demonstrated by a write operation on an AF_ALG socket.
