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...

CVE-2026-63911 xfrm: iptfs: reset runtime state when cloning SAs

In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: reset runtime state when cloning SAs iptfsclonestate clones the IPTFS mode data with kmemdup. This copies runtime objects which must not be shared with the original SA, including the embedded skbuffhead, hrtimers,...
