CVE-2023-54285

An integer overflow vulnerability was found in the iomap subsystem. On 32-bit systems, calculating folio positions could overflow when large folios are used, potentially causing incorrect delalloc extent scanning.

This affects 32-bit systems only, which are uncommon in modern deployments. The overflow requires specific memory and filesystem conditions to trigger and would result in incorrect I/O mapping rather than direct security impact.
