CVE-2026-68420

CVE-2026-68420 concerns the Linux kernel xfrm subsystem. The issue is a stack-out-of-bounds read triggered when an outbound IPsec policy uses optional IPTFS templates, flowing from xfrm_tmpl_resolve_one() and xfrm_state_find() via the outbound path. The fix extends previous checks that blocked op...
