Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: ceph: put folios not suitable for writeback The batch holds references to the folios (see `filemap_get_folios`, `folio_batch_release`), so we need to `folio_put` the folios we remove. Tested on v6.18.

Executive Summary

This vulnerability in the Linux kernel relates to the Ceph file system's handling of folios during writeback operations. Specifically, the issue involves the improper management of folio references within a batch. The batch holds references to folios, and when folios are removed, they need to be properly released using the folio_put function. Failure to do so could lead to incorrect reference counting and potential memory management issues.

Impact Analysis

Improper handling of folio references in the Ceph file system could lead to memory leaks or corruption within the Linux kernel. This may affect system stability or data integrity when using Ceph storage. However, specific impacts such as exploitation scenarios or severity are not detailed.
