CVE-2010-4073

Linux Kernel < 2.6.37 - Information Disclosure via Uninitialized IPC Structures

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2010-4073. PoCs published by Jon Oberheide.

AI-analyzed exploit summary This exploit leverages multiple Linux kernel vulnerabilities (CVE-2010-3848, CVE-2010-3850, CVE-2010-4073) to achieve local privilege escalation via a kernel stack overflow in the Econet protocol implementation. It uses a combination of stack manipulation and symbol resolution to overwrite kernel memory and escalate privileges.

Description

The ipc subsystem in the Linux kernel before 2.6.37-rc1 does not initialize certain structures, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c.
