Description OSIDB Bzimport 2026-06-24 18:01:51 UTC 
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.
