"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: don't let hidden_space go negative in xfs_metafile_resv_init\n\nLOLLM points out that if the amount of fdblocks that we can reserve for\na metadata btree file goes below the space already used by that file,\nthen the hidden_space subtraction can underflow, causing\nxfs_dec_fdblocks to subtract a huge amount of space. We never want the\ntarget to be less than the used sapce, so fix the logic that adjusts\ndblocks_avail downwards.\n\nAlso fix an error in the adjacent comment."
