CVE-2026-46052

A flaw was found in the Linux kernel's Ceph filesystem. A local user or process interacting with the Ceph filesystem could trigger a dcache hash corruption when a negative dentry is incorrectly re-added to the dcache hash while it is already present. This can cause the system to experience an RCU...
