In the Linux kernel, the following vulnerability has been resolved:

jfs: handle set_blocksize failures

jfs uses buffer_heads, which don't handle block size > PAGE_SIZE well. Without this, mounting we will hit the

    BUG_ON(offset >= folio_size(folio));

in folio_set_bh on the first __bread_gfp call.
