"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject struct_ops registration that uses module ptr and the module btf_id is missing\n\nThere is a UAF report in the bpf_struct_ops when CONFIG_MODULES=n.\nIn particular, the report is on tcp_congestion_ops that has\na \"struct module *owner\" member.\n\nFor struct_ops that has a \"struct module *owner\" member,\nit can be extended either by the regular kernel module or\nby the bpf_struct_ops. bpf_try_module_get() will be used\nto do the refcounting and different refcount is done\nbased on the owner pointer. When CONFIG_MODULES=n,\nthe btf_id of the \"struct module\" is missing:\n\nWARN: resolve_btfids: unresolved symbol module\n\nThus, the bpf_try_module_get() cannot do the correct refcounting.\n\nNot all subsystem's struct_ops requires the \"struct module *owner\" member.\ne.g. the recent sched_ext_ops.\n\nThis patch is to disable bpf_struct_ops registration if\nthe struct_ops has the \"struct module *\" member and the\n\"struct module\" btf_id is missing. The btf_type_is_fwd() helper\nis moved to the btf.h header file for this test.\n\nThis has happened since the beginning of bpf_struct_ops which has gone\nthrough many changes. The Fixes tag is set to a recent commit that this\npatch can apply cleanly. Considering CONFIG_MODULES=n is not\ncommon and the age of the issue, targeting for bpf-next also."

"value": "AV:L - The attack is driven entirely through local syscalls — bpf(BPF_MAP_CREATE/MAP_UPDATE_ELEM/LINK_CREATE) to register the struct_ops congestion control, setsockopt(TCP_CONGESTION) to bind a socket to it, and close() to drop the map. Although the freed object is subsequently dereferenced while processing TCP ACKs, a remote peer cannot perform the registration/free setup.\nAC:L - On an affected kernel every step is deterministic and attacker-driven — register the struct_ops, attach it to a socket the attacker owns, close the fds to free the map, then drive traffic over loopback to hit the dangling icsk_ca_ops; there is no race and no dependence on memory layout the attacker cannot influence. The build-time CONFIG_MODULES=n precondition defines the vulnerable configuration rather than a condition to be won at exploit time, and it is trivially observable in advance (absent /proc/modules).\nPR:L - Creating the struct_ops map goes through bpf_token_capable(token, CAP_BPF), which BPF tokens explicitly delegate into unprivileged container user namespaces — the model container runtimes and BPF agents routinely use — and the socket, setsockopt(TCP_CONGESTION) and loopback-traffic halves of the attack need no capability at all.\nUI:N - The attacker performs the entire sequence with its own process, sockets and file descriptors; no victim action, mount, or configuration change by another user is required.\nS:U - The dangling tcp_congestion_ops pointer is dereferenced by the same kernel the attacker already has local access to; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed st_map allocation holding kvalue.data can be reclaimed and shaped by the attacker while sockets still read through icsk_ca_ops, turning the stale pointer into a controlled kernel-memory read primitive that leaks arbitrary kernel data.\nI:H - The kernel makes indirect calls through function pointers in the freed tcp_congestion_ops and into freed trampoline/bpf_prog_pack executable pages, giving a direct control-flow hijack primitive after heap or exec-page reclaim — full arbitrary write and code execution in kernel context.\nA:H - Even unweaponized, the use-after-free causes an oops or panic on the next congestion-control callback, and installing the bpf CA as the netns default poisons every new TCP socket in that namespace, wedging the network stack."
