CVE-2006-5174
First published: Thu Oct 05 2006(Updated: )
The copy_from_user function in the uaccess code in Linux kernel 2.6 before 2.6.19-rc1, when running on s390, does not properly clear a kernel buffer, which allows local user space programs to read portions of kernel memory by "appending to a file from a bad address," which triggers a fault that prevents the unused memory from being cleared in the kernel buffer.

Frequently Asked Questions
What is the severity of CVE-2006-5174?
The severity of CVE-2006-5174 is considered medium due to its potential to expose sensitive kernel memory to local users.
How do I fix CVE-2006-5174?
To fix CVE-2006-5174, upgrading the Linux kernel to version 2.6.19 or later is recommended.
What are the impacts of CVE-2006-5174?
CVE-2006-5174 allows local user space programs to read portions of kernel memory, potentially leading to unauthorized data access.
Which systems are affected by CVE-2006-5174?
CVE-2006-5174 affects the Linux kernel versions prior to 2.6.19 especially on s390 architectures.
Is CVE-2006-5174 remotely exploitable?
CVE-2006-5174 is not remotely exploitable as it requires local access to the affected system.
