Description
In the Linux kernel, the following vulnerability has been resolved:
isofs: handle set_blocksize failures
isofs 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.
