Exploitation Summary

EIP tracks 1 public exploit for CVE-2004-1335. PoCs published by Georgi Guninski.

AI-analyzed exploit summary This exploit targets an integer overflow in the Linux kernel's `ip_options_get` function (CVE-2004-1335) by crafting a malicious `cmsghdr` structure with a negative `cmsg_len` to trigger a kernel panic or potential code execution. The PoC sends a specially crafted `sendmsg` call with manipulated control message headers to exploit the vulnerability.

Description

Memory leak in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ip_cmsg_send function.
