CVE-2018-18690

kernel: filesystem corruption due to an unchecked error condition during an xfs attribute change

Published Oct 26, 2018 CVSS 3.0 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
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.
