CVE-2026-68415
A flaw was found in the Linux kernel's xfrm IPSec framework component. A vulnerability exists where the xfrmstategctask can attempt to dereference stale callback data after a failed Internet Protocol Traffic Flow Security IPTFS state setup and subsequent module unload. This can lead to a kernel...
CVE-2026-68420
A flaw was found in the Linux kernel's xfrm component. A local user could trigger a stack-out-of-bounds read by configuring an outbound Internet Protocol Security IPsec policy with optional IPsec Flow Template Specification IPTFS templates. This vulnerability can lead to a system crash, resulting...

CVE-2026-68420
The CVE affects the Linux kernel xfrm outbound policy handling. A stack-out-of-bounds read in __xfrm6_addr_hash was triggered via xfrm_state_find and xfrm_tmpl_resolve_one when using IPTFS templates in outbound policies. A prior fix already disallowed optional tunnel/BEET templates in outbound po...

CVE-2026-64566
A flaw was found in the Linux kernel's iptfs module, which handles network packet processing. When copying shared packet fragments, a critical flag indicating shared memory is not correctly propagated. This can lead to memory corruption within the kernel, potentially causing the system to crash a...

CVE-2026-64566 xfrm: iptfs: propagate SKBFL_SHARED_FRAG in iptfs_skb_add_frags()
In the Linux kernel, the following vulnerability has been resolved: xfrm: iptfs: propagate SKBFLSHAREDFRAG in iptfsskbaddfrags When iptfsskbaddfrags copies frag references from the source frag walk into a new SKB, it increments the page reference count via skbfragref but does not propagate...
CVE-2026-64566
Consolidated details show CVE-2026-64566 affects the Linux kernel iptfs module. Root cause: when iptfs_skb_add_frags() copies frag references, it increments page refs without propagating SKBFL_SHARED_FRAG to the destination SKB, unlike other frag-transfer helpers. Consequence: if source SKB has s...

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...
