CVE-2026-23333

Rejected record with no confirmed security issue

Published Mar 25, 2026 · Updated Mar 25, 2026

CVE-2026-23333 is rejected and no longer identifies a confirmed vulnerability in the Linux Kernel or any other product. The kernel CNA withdrew the record and removed its sole patch reference after initially describing nft_set_rbtree open-interval overlap validation. The former description and version ranges therefore must not be treated as current vulnerability or product-applicability claims.
