Deskripsi CVE
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.
