In the Linux kernel, the following vulnerability has been resolved:
erofs: set fileio bio failed in short read case
For file-backed mount, IO requests are handled by vfs_iocb_iter_read().
However, it can be interrupted by SIGKILL, returning the number of
bytes actually copied. Unused folios in bio are unexpectedly marked
as uptodate.
vfs_read
filemap_read
filemap_get_pages
filemap_readahead
erofs_fileio_readahead
erofs_fileio_rq_submit
vfs_iocb_iter_read
filemap_read
filemap_get_pages <= detect signal
erofs_fileio_ki_complete <= set all folios uptodate
This patch addresses this by setting short read bio with an error
directly.
