"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncifs: don't update i_size in cifs_do_truncate without a cached handle\n\nIf find_writable_file() returns null, cifs_file_flush will return\n0 without issuing set_file_size, and the outer 'if (!rc)' block\nwill set i_size to 0 before telling the server to truncate. If\nthe cifs_open() then fails, the inode will have size 0, while\nthe server file is unchanged.\n\nMove the netfs_resize_file() and cifs_setsize() into the 'if\n(cfile)', so they only run after a successful set_file_size.\n\nIn the no-handle else branch, evict stale pages with\ntruncate_inode_pages before the O_TRUNC open to dispose of old\ncache pages, and let the open response set the i_size."
