  3. CVE-2023-52682
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

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: f2fs: corrección para esperar en la reescritura del bloque para el caso post_read. Si el inodo está comprimido, pero no encriptado, no llamó a f2fs_wait_on_block_writeback() para esperar la reescritura de la página GCed en la ruta de escritura de la IPU. Subproceso A GC-Thread - f2fs_gc - do_garbage_collect - gc_data_segment - move_data_block - f2fs_submit_page_write migra el bloque del clúster normal a través del caché de página de meta_inode - f2fs_write_single_data_page - f2fs_do_write_data_page - f2fs_inplace_write_data - f2fs_submit_page_bio IRQ - fs_read_end_io Los datos antiguos de IRQ anulan los datos nuevos debido a GC desordenado y común OÍ. - f2fs_read_end_io
