FKIE_CVE-2014-0203

Vulnerability from fkie_nvd - Published: 2014-06-23 11:21 - Updated: 2026-06-17 00:02
Summary
The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the last pathname component during use of certain filesystems, which allows local users to cause a denial of service (incorrect free operations and system crash) via an open system call.
