  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nblock: refine the EOF check in blkdev_iomap_begin\n\nblkdev_iomap_begin rounds down the offset to the logical block size\nbefore stashing it in iomap->offset and checking that it still is\ninside the inode size.\n\nCheck the i_size check to the raw pos value so that we don't try a\nzero size write if iter->pos is unaligned.",
