  "details": "In the Linux kernel, the following vulnerability has been resolved:  xfs: fix exchmaps reservation limit check  xfs_exchmaps_estimate_overhead() adds the bmbt and rmapbt overhead to a local resblks variable, but the final UINT_MAX check still tests req-\u003eresblks.  That is the reservation value from before the overhead was added.  The computed value is stored back in req-\u003eresblks and later passed to xfs_trans_alloc(), whose block reservation argument is unsigned int.  Check the computed reservation so the existing limit applies to the value that will be used.",
