CVE-2010-0437
Linux Kernel < 2.6.27 - Denial of Service via IPv6 TUN Network Interface
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2010-0437. PoCs published by Rémi Denis-Courmont.
AI-analyzed exploit summary This exploit targets a local denial-of-service vulnerability in the Linux kernel by creating a TUN/TAP interface and flooding it with IPv6 packets, potentially causing a kernel crash. The PoC demonstrates the issue by spawning threads that send UDP packets and read from the TUN device.
Description
The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.
