"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: take invalidate_lock in ntfs_filemap_page_mkwrite()\n\nntfs_filemap_page_mkwrite() calls iomap_page_mkwrite() without holding\nmapping->invalidate_lock, so a concurrent truncate or fallocate can be\nin the middle of invalidating pagecache and rewriting the runlist while\nthe write fault maps blocks and dirties the folio. This races with\nntfs_attr_fallocate(), which merges clusters into the in-memory\nrunlist, drops the runlist lock, and only afterwards zeroes the newly\nallocated clusters on disk; and with the punch-hole/insert/collapse\npaths that free clusters after truncating the cache.\n\nPer Documentation/filesystems/locking.rst, ->page_mkwrite() must ensure\nthere are no truncate/invalidate races, \"usually mapping->invalidate_lock\nis suitable for proper serialization\". xfs takes its mmaplock (= the\ninvalidate_lock rwsem) shared in exactly this path.\n\nTake invalidate_lock shared around iomap_page_mkwrite(). The read-only\nfault path is already covered because filemap_fault() itself grabs\ninvalidate_lock shared on instantiation/read paths; only page_mkwrite\nwas bypassing it in this driver."
