CVE-2022-50487

Record rejected by assigning CNA

Published Oct 4, 2025 · Updated Oct 4, 2025

CVE-2022-50487 no longer identifies a Linux Kernel vulnerability because the assigning CNA rejected and withdrew the record. The withdrawn description attributed an NFSD NFSv3 READDIR send-buffer overflow to oversized TCP RPC records shrinking svc_rqst::rq_res, but the rejection removed the kernel references. No confirmed affected range or triageable security issue remains under this identifier; historical downstream assessments do not restore CVE validity.
