- Summary
- btrfs: protect sb_write_pointer() with invalidate lock
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: protect sb_write_pointer() with invalidate lock
sb_write_pointer() reads the super block from the block device page cache using read_cache_page_gfp(). This has the same race with BLKBSZSET as the one fixed by commit 3f29d661e568 ("btrfs: sync read disk super and set block size").
Take the mapping invalidate lock around read_cache_page_gfp() to serialize the read against block size changes.
