    Added Description In the Linux kernel, the following vulnerability has been resolved:

    iomap: avoid avoid truncating 64-bit offset to 32 bits

    on 32-bit kernels, iomap_write_delalloc_scan() was inadvertently using a
    32-bit position due to folio_next_index() returning an unsigned long.
    This could lead to an infinite loop when writing to an xfs filesystem.
