- Summary
- [none]
- Details
-
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 xfsattrshortformaddname in fs/xfs/libxfs/xfsattr.c mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.
