CVE-2026-63911

CVE-2026-63911 (Linux kernel xfrm/iptfs) : The vulnerability arises in how IPTFS mode data is cloned during SA cloning. iptfs_clone_state() duplicates runtime objects (e.g., sk_buff_head, hrtimers, spinlocks, reassembly/reorder state) via kmemdup, which must not be shared with the original SA. If...
