Title
ip_vti: fix potential slab-use-after-free in decode_session6
Summary
In the Linux kernel, the following vulnerability has been resolved:
ip_vti: fix potential slab-use-after-free in decode_session6
When ip_vti device is set to the qdisc of the sfb type, the cb field
of the sent skb may be modified during enqueuing. Then,
slab-use-after-free may occur when ip_vti device sends IPv6 packets.
As commit f855691975bb ("xfrm6: Fix the nexthdr offset in
_decode_session6.") showed, xfrm_decode_session was originally intended
only for the receive path. IP6CB(skb)->nhoff is not set during
transmission. Therefore, set the cb field in the skb to 0 before
sending packets.

"value": "AV:L - Triggering requires a locally configured ip_vti device with an sfb qdisc attached and packets routed out of it, all of which is set up and driven through local netlink/rtnetlink and a local socket. Although forwarded traffic from a remote peer would also hit vti_tunnel_xmit on a router so configured, the vulnerable state depends entirely on local device/qdisc configuration, so Local is the defensible vector.\nAC:L - The attacker creates every precondition: the vti device, the sfb qdisc, and its rehash_interval/warmup_time tunables that control when q-\u003eslot flips and hashes[1] is populated with a siphash value overlapping IP6CB-\u003enhoff. Once slot==1 every transmitted IPv6 packet performs the wild nh[nhoff] read, making the trigger deterministic and repeatable.\nPR:L - Creating the vti tunnel and attaching the sfb qdisc requires CAP_NET_ADMIN, but ip_vti is fully network-namespace aware (register_pernet_device with a per-netns ip_vti0 fallback), so an unprivileged user obtains the needed capability with unshare -Urn. Per kernel scoring guidance, CAP_NET_ADMIN reachable through user namespaces is Low, not High.\nUI:N - The attacker performs the entire sequence \u2014 configure the device and qdisc, add a route, send an IPv6 packet \u2014 with no action by any other user or administrator.\nS:U - The out-of-bounds access occurs in kernel heap memory and its consequences remain within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - decode_session6() reads a byte from freed or adjacent slab memory at an offset up to 64KB beyond the network header \u2014 an unbounded use-after-free read rather than a small bounded one \u2014 and that value steers the protocol state machine and xfrm flow key, providing an oracle on kernel heap contents.\nI:H - The kernel\u0027s IPsec flow decode (flowi6_proto, ports, and the ensuing ip6_route_output/xfrm_lookup_route policy selection) is driven by data read out of freed heap memory, so a security-relevant kernel decision is made on corrupted state; consistent with treating slab-use-after-free as a high integrity impact.\nA:H - The wild read dereferences an address up to 65535 bytes past the skb data allocation, which faults on unmapped memory or memory holes and reliably produces a KASAN slab-use-after-free splat and kernel oops. The attacker can repeat it on every transmitted packet, so it is a sustained crash/DoS."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
