CVE-2013-4125 WRITEUP WRITEUP
Linux Kernel < 3.10.1 - Denial of Service via IPv6 Router Advertisement Handling
The fib6_add_rt2node function in net/ipv6/ip6_fib.c in the IPv6 stack in the Linux kernel through 3.10.1 does not properly handle Router Advertisement (RA) messages in certain circumstances involving three routes that initially qualified for membership in an ECMP route set until a change occurred for one of the first two routes, which allows remote attackers to cause a denial of service (system crash) via a crafted sequence of messages.
CVE-2013-4162 WRITEUP WRITEUP
Linux Kernel < 3.10.3 - Denial of Service via UDP_CORK Option in IPv6 Implementation
The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call.
CVE-2013-4163 WRITEUP WRITEUP
Linux Kernel < 3.10.3 - Denial of Service via IPv6 MTU Option Handling
The ip6_append_data_mtu function in net/ipv6/ip6_output.c in the IPv6 implementation in the Linux kernel through 3.10.3 does not properly maintain information about whether the IPV6_MTU setsockopt option had been specified, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call.
CVE-2013-4387 WRITEUP WRITEUP
Linux Kernel < 3.11.4 - Denial of Service via UDP Fragmentation Offload Processing
net/ipv6/ip6_output.c in the Linux kernel through 3.11.4 does not properly determine the need for UDP Fragmentation Offload (UFO) processing of small packets after the UFO queueing of a large packet, which allows remote attackers to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via network traffic that triggers a large response packet.
CVE-2013-4563 WRITEUP WRITEUP
Linux Kernel < 3.12 - Denial of Service via UDP Fragmentation Offload
The udp6_ufo_fragment function in net/ipv6/udp_offload.c in the Linux kernel through 3.12, when UDP Fragmentation Offload (UFO) is enabled, does not properly perform a certain size comparison before inserting a fragment header, which allows remote attackers to cause a denial of service (panic) via a large IPv6 UDP packet, as demonstrated by use of the Token Bucket Filter (TBF) queueing discipline.
CVE-2015-1465 WRITEUP WRITEUP
Linux Kernel 3.10.50-3.10.69 - Denial of Service via IPv4 RCU Grace Period Mismanagement
The IPv4 implementation in the Linux kernel before 3.18.8 does not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allows remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets.
