DATE CVE VULNERABILITY TITLE RISK
2013-07-16 CVE-2013-1943 Improper Input Validation vulnerability in multiple products
The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c.

2012-05-24 CVE-2011-3191 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Integer signedness error in the CIFSFindNext function in fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large length value in a response to a read request for a directory.

linux redhat CWE-119
8.8
2012-05-24 CVE-2011-2699 The IPv6 implementation in the Linux kernel before 3.1 does not generate Fragment Identification values separately for each destination, which makes it easier for remote attackers to cause a denial of service (disrupted networking) by predicting these values and sending crafted packets.

2012-05-17 CVE-2012-1097 NULL Pointer Dereference vulnerability in multiple products
The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.

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.

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.

linux redhat canonical debian CWE-400
7.5
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.

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.

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.
7.8
2010-09-24 CVE-2010-1773 Off-by-one Error vulnerability in multiple products
Off-by-one error in the toAlphabetic function in rendering/RenderListMarker.cpp in WebCore in WebKit before r59950, as used in Google Chrome before 5.0.375.70, allows remote attackers to obtain sensitive information, cause a denial of service (memory corruption and application crash), or possibly execute arbitrary code via vectors related to list markers for HTML lists, aka rdar problem 8009118.
