in the corrupted image, there is a dnode has the same\nnode id w/ its inode, so during f2fs_get_dnode_of_data(), it tries to\naccess block address in dnode at offset 934, however it parses the dnode\nas inode node, so that get_dnode_addr() returns 360, then it tries to\naccess page address from 360 + 934 * 4 = 4096 w/ 4 bytes.\n\nTo fix this issue, let's add sanity check for node id of all direct nodes\nduring f2fs_get_dnode_of_data()." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
