Summary
In the Linux kernel, the following vulnerability has been resolved: ipv6: use RCU in ip6_output() Use RCU in ip6_output() in order to use dst_dev_rcu() to prevent possible UAF. We can remove rcu_read_lock()/rcu_read_unlock() pairs from ip6_finish_output2().

(Even in the purely local framing the netns/CAP_NET_ADMIN half is obtainable via `unshare -Urn`, so no real privilege is required either way.)\nUI:N - Transmission and forwarding happen unconditionally in softirq/process context on packet arrival; no administrator or local user has to open, mount, or click anything.\nS:U - The freed `inet6_dev` and `net_device` are kernel objects and the corruption stays within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of `idev-\u003ecnf.disable_ipv6`, `idev-\u003estats.ipv6`, `dev-\u003ehard_header_len`/`needed_headroom`, `dev-\u003eheader_ops` and `dev-\u003eflags`; once the freed slab object is reallocated the attacker can steer header-expansion sizes and the egress device, yielding kernel memory disclosure and out-of-device packet leakage.\nI:H - `IP6_INC_STATS`/`IP6_UPD_PO_STATS` expand to `SNMP_INC_STATS64(idev-\u003estats.ipv6, field)`, performing a 64-bit increment through a per-CPU pointer loaded from freed memory \u2014 an arbitrary-write primitive after reallocation \u2014 and `neigh_output()` \u2192 `dev_queue_xmit()` makes an indirect call through `dev-\u003enetdev_ops-\u003endo_start_xmit` read from the freed `net_device`, giving control-flow hijack.\nA:H - Dereferencing a freed `inet6_dev`/`net_device` on the packet transmit path reliably oopses or panics the kernel (KASAN slab-use-after-free), and the crash is in the core IPv6 output path so it takes down the whole forwarding host."
