CVE-2018-18690 (GCVE-0-2018-18690)

Vulnerability from cvelistv5 – Published: 2018-10-26 18:00 – Updated: 2024-08-05 11:16

Summary

In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.

Severity ?

No CVSS data available.
