## Overview

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

omfs: handle set_blocksize failures

omfs 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.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
