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...
