Description

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to wait on block writeback for post_read case If inode is compressed, but not encrypted, it missed to call f2fs_wait_on_block_writeback() to wait for GCed page writeback in IPU write path. Thread A GC-Thread - f2fs_gc - do_garbage_collect - gc_data_segment - move_data_block - f2fs_submit_page_write migrate normal cluster's block via meta_inode's page cache - f2fs_write_single_data_page - f2fs_do_write_data_page - f2fs_inplace_write_data - f2fs_submit_page_bio IRQ - f2fs_read_end_io IRQ old data overrides new data due to out-of-order GC and common IO. - f2fs_read_end_io
