| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: drop ppath from ext4_ext_replay_update_ex() to avoid double-free\n\nWhen calling ext4_force_split_extent_at() in ext4_ext_replay_update_ex(),\nthe 'ppath' is updated but it is the 'path' that is freed, thus potentially\ntriggering a double-free in the following process:\n\next4_ext_replay_update_ex\n ppath = path\n ext4_force_split_extent_at(&ppath)\n ext4_split_extent_at\n ext4_ext_insert_extent\n ext4_ext_create_new_leaf\n ext4_ext_grow_indepth\n ext4_find_extent\n if (depth > path[0].p_maxdepth)\n kfree(path) ---> path First freed\n *orig_path = path = NULL ---> null ppath\n kfree(path) ---> path double-free !!!\n\nSo drop the unnecessary ppath and use path directly to avoid this problem.\nAnd use ext4_find_extent() directly to update path, avoiding unnecessary\nmemory allocation and freeing. Also, propagate the error returned by\next4_find_extent() instead of using strange error codes." |
