CVE-2026-53212

The CVE-2026-53212 issue affects the Linux kernel nft_tunnel implementation within netfilter, where nft_tunnel_obj_destroy() used metadata_dst_free() to free a metadata_dst, bypassing dst_entry refcount accounting. This could leave in-flight packets that hold references (via dst_hold()) dangling,...
