"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfsd: check client ownership when cancelling a copy-notify stateid\n\nOn the OFFLOAD_CANCEL path (clp != NULL), manage_cpntf_state() freed the\ntarget cpntf state without checking ownership. The lookup key\nst->si_opaque.so_id is allocated cyclically (guessable) and the embedded\nclientid is the fixed per-net nn->s2s_cp_cl_id, so any authenticated\nNFSv4.2 client could cancel and free another client's copy-notify\nstateid.\n\nCompare the creating clientid recorded in state->cp_p_clid against the\nrequesting client's cl_clientid and return nfserr_bad_stateid on a\nmismatch instead of freeing the entry."
