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...
