Vulnerability from github – Published: 2024-06-19 15:30 – Updated: 2025-10-03 15:31

Details

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

block: refine the EOF check in blkdev_iomap_begin

blkdev_iomap_begin rounds down the offset to the logical block size before stashing it in iomap->offset and checking that it still is inside the inode size.

Check the i_size check to the raw pos value so that we don't try a zero size write if iter->pos is unaligned.

Severity ?

5.5 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
