CVE-2026-89647

CVE-2026-89647 affects the Linux kernel's Ceph file system . The function ceph_cap_reclaim_work() enters a busy loop by re-queuing itself whenever ceph_trim_dentries() returns -EAGAIN, which occurs when a lease walk exhausts its scan budget with no cap pressure and all leases still valid. The dir...
