CVE-2026-89681

A race condition in the Linux kernel's nfsd component (the NFS server daemon) affects the layout fence worker. Because the workqueue core clears WORK_STRUCT_PENDING before invoking the callback, delayed_work_pending() in lm_breaker_timedout() can return false while a fence worker is already runni...

CVE-2026-89677

CVE-2026-89677 affects the Linux kernel NFS daemon (nfsd) subsystem, specifically the nfsd4_create_file() function. The root cause is that dentry_create() can return a dentry different from the one expected — for instance, when the exported filesystem is NFS and the server returns a filehandle ma...

CVE-2026-89676

CVE-2026-89676 affects the Linux kernel nfsd (Network File System Daemon) component.
