Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: netfilter: complete validation of user input In my recent commit, I missed that do_replace() handlers use copy_from_sockptr() (which I fixed), followed by unsafe copy_from_sockptr_offset() calls. In all functions, we can perform the @optlen validation before even calling xt_alloc_table_info() with the following check: if ((u64)optlen < (u64)tmp.size + sizeof(tmp)) return -EINVAL;

No network packet or remote peer data reaches this code path.\nAC:L - The attacker fully controls `tmp.size` and `optlen` and triggers the oversized `memcpy()` deterministically on every call \u2014 no race, no memory-layout luck, and no retry needed. The kernel-sockptr precondition is satisfied by any attached cgroup/setsockopt BPF program (even a no-op one, since `ctx.optlen` defaults to the original `optlen`), which is standard in container environments running Cilium and similar tooling on default `CONFIG_CGROUP_BPF=y` kernels.\nPR:L - `do_ipt_set_ctl()` gates on `ns_capable(sock_net(sk)-\u003euser_ns, CAP_NET_ADMIN)`, which any unprivileged user obtains with `unshare -Urn`; entering a new user/net namespace leaves cgroup membership intact so the BPF sockopt hook still applies. No real root in the initial namespace is required.\nUI:N - The attacker performs the entire sequence \u2014 socket creation, namespace setup, and the malformed setsockopt call \u2014 with no action by any other user or victim process.\nS:U - The out-of-bounds read occurs in kernel slab memory and its impact is confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is an unbounded out-of-bounds read \u2014 up to `XT_MAX_TABLE_SIZE` (512 MB) copied from a \u2264PAGE_SIZE slab object into the netfilter table buffer, far beyond a \"few bytes\".
