"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix BUG in nilfs_copy_dirty_pages() on dirty state mismatch\n\nSyzbot reported a kernel BUG triggered within nilfs_copy_dirty_pages(),\nwhich copies dirty DAT file folios/pages to its shadow page cache. The\nBUG occurs when a retrieved dirty folio/page unexpectedly loses its\n'dirty' status.\n\nThis issue arises because, since the commit referenced below, the 'dirty'\nflag of a folio/page can be cleared asynchronously after the filesystem\ndetects metadata corruption and transitions to read-only mode.\n\nResolve the issue by returning an -EROFS error if the filesystem has\ntransitioned to read-only mode. Also change the behavior to issue a\nkernel warning only once instead of triggering a kernel BUG when this\nunexpected 'dirty' state is detected while the filesystem is not in\nread-only mode."
