CVE-2026-89683

CVE-2026-89683 affects the Linux kernel 's nfsd subsystem. The flaw is in nfsd_set_fh_dentry(), which leaks a dentry reference obtained from exportfs_decode_fh_raw() when the NFS3_FHSIZE or NFS_FHSIZE switch cases detect NFSEXP_V4ROOT and jump to the out: label. That label calls exp_put() but nev...
