  "details": "In the Linux kernel, the following vulnerability has been resolved:  xfs: don't let hidden_space go negative in xfs_metafile_resv_init  LOLLM points out that if the amount of fdblocks that we can reserve for a metadata btree file goes below the space already used by that file, then the hidden_space subtraction can underflow, causing xfs_dec_fdblocks to subtract a huge amount of space.  We never want the target to be less than the used sapce, so fix the logic that adjusts dblocks_avail downwards.  Also fix an error in the adjacent comment.",
