Description
In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to truncate meta inode pages forcely
Below race case can cause data corruption:
Thread A GC thread
- gc_data_segment
- ra_data_block
- locked meta_inode page
- f2fs_inplace_write_data
- invalidate_mapping_pages
: fail to invalidate meta_inode page
due to lock failure or dirty|writeback
status
- f2fs_submit_page_bio
: write last dirty data to old blkaddr
- move_data_block
- load old data from meta_inode page
- f2fs_submit_page_write
: write old data to new blkaddr
Because invalidate_mapping_pages() will skip invalidating page which
has unclear status including locked, dirty, writeback and so on, so
we need to use truncate_inode_pages_range() instead of
invalidate_mapping_pages() to make sure meta_inode page will be dropped.
Affected configurations
• linux linux kernel (>= 4.19 < 6.6.23)
• linux linux kernel (>= 6.7 < 6.7.11)
• linux linux kernel (>= 6.8 < 6.8.2)
