FKIE_CVE-2014-7283

Vulnerability from fkie_nvd - Published: 2014-10-13 10:55 - Updated: 2026-06-17 00:14
Severity
Summary
The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the xfs implementation in the Linux kernel before 3.14.2 does not properly compare btree hash values, which allows local users to cause a denial of service (filesystem corruption, and OOPS or panic) via operations on directories that have hash collisions, as demonstrated by rmdir operations.
