CVE-2026-52960 Details
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.
A vulnerability has been identified in the Linux kernel's Ceph module, specifically in versions through 6.18. The issue arises in the handling of folio references during batch processing. The batch can retain references to folios, which necessitates proper management to avoid memory issues. The vulnerability has been addressed by ensuring that folios removed from the batch are correctly released, preventing potential memory leaks or corruption.
Users can upgrade to the latest version of the Linux kernel to address this vulnerability. The patched version is available in the Linux kernel stable tree.
