https://notcve.org/view.php?id=CVE-2018-18690
26 Oct 2018 — 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. En el kernel de Linux en versiones anteriores a la 4.17, un atacante local que sea capaz de establecer atributos en un sistema de... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7b38460dc8e4eafba06c78f8e37099d3b34d473c • CWE-391: Unchecked Error Condition CWE-754: Improper Check for Unusual or Exceptional Conditions •
