Summary

In the Linux kernel netfs module, error handling in the writeback_iter() loop is incorrect. If an error occurs, writeback_iter() needs to be called again with the error set to clean up iteration state, and the current folio needs unlocking and redirtying.

Risk Assessment

Incorrect error handling can lead to data loss or inconsistency during writeback.

Recommendation

Apply a Linux kernel update that includes the fix for this vulnerability.
