CVE-2026-89646

CVE-2026-89646 is a leaked inode reference bug in the Ceph filesystem component of the Linux kernel. When a writeback is aborted during unmount (because ceph_inc_osd_stopping_blocker() fails), the ihold() taken by ceph_dirty_folio() is never released via writepages_finish(), so i_wrbuffer_ref nev...
