"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: fix exchmaps reservation limit check\n\nxfs_exchmaps_estimate_overhead() adds the bmbt and rmapbt\noverhead to a local resblks variable, but the final UINT_MAX\ncheck still tests req->resblks. That is the reservation value\nfrom before the overhead was added.\n\nThe computed value is stored back in req->resblks and later passed\nto xfs_trans_alloc(), whose block reservation argument is unsigned\nint. Check the computed reservation so the existing limit applies\nto the value that will be used."
