CVE-2026-89676

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. When performing an asynchronous async copy operation, a programming error causes a stale identifier IDR entry to point to memory that has already been reused. This can lead to memory corruption, where the system...

CVE-2026-89676

CVE-2026-89676 affects the Linux kernel nfsd (NFS server) component. During an asynchronous COPY operation, nfsd4_copy() called nfs4_init_copy_state() before dup_copy_fields(), causing the s2s_cp_stateids IDR to reference a transient per-request COMPOUND buffer rather than the stable async_copy s...
