Summary

In the Linux kernel, the following vulnerability has been resolved: bpf: Add sk_is_inet and IS_ICSK check in tls_sw_has_ctx_tx/rx As the introduction of the support for vsock and unix sockets in sockmap, tls_sw_has_ctx_tx/rx cannot presume the socket passed in must be IS_ICSK. vsock and af_unix sockets have vsock_sock and unix_sock instead of inet_connection_sock. For these sockets, tls_get_ctx may return an invalid pointer and cause page fault in function tls_sw_ctx_rx. BUG: unable to handle page fault for address: 0000000000040030 Workqueue: vsock-loopback vsock_loopback_work RIP: 0010:sk_psock_strp_data_ready+0x23/0x60 Call Trace: ? __die+0x81/0xc3 ? no_context+0x194/0x350 ? do_page_fault+0x30/0x110 ? async_page_fault+0x3e/0x50 ? sk_psock_strp_data_ready+0x23/0x60 virtio_transport_recv_pkt+0x750/0x800 ? update_load_avg+0x7e/0x620 vsock_loopback_work+0xd0/0x100 process_one_work+0x1a7/0x360 worker_thread+0x30/0x390 ? create_worker+0x1a0/0x1a0 kthread+0x112/0x130 ? __kthread_cancel_work+0x40/0x40 ret_from_fork+0x1f/0x40 v2: - Add IS_ICSK check v3: - Update the commits in Fixes

Despite living in include/net/tls.h, no TLS/kTLS network peer is involved; the helper is simply misapplied to non-inet sockets.\nAC:L - The attacker deterministically controls both the configuration (sockmap with stream_parser+stream_verdict, or the sk_skb_adjust_room helper) and the trigger (writing to the socket); no race and no uncontrolled memory layout is required. The confused offset is fixed and the fault reproduces reliably, as shown by the reporter\u0027s vsock-loopback repro.\nPR:L - In the intended deployment for this feature \u2014 sockmap acceleration of AF_UNIX/vsock IPC set up by a privileged agent \u2014 an ordinary unprivileged local process triggers the OOB read merely by connecting and writing to the socket, and a guest VM can trigger the identical virtio_transport_recv_pkt path on the host. BPF tokens (6.9+) additionally let container runtimes delegate CAP_BPF/CAP_NET_ADMIN into an unprivileged user namespace, so real init-namespace root is not required.\nUI:N - No victim action is needed; the attacker performs both the sockmap attachment (or relies on an existing legitimate one) and the socket write that drives sk_data_ready into the confused helper.\nS:U - The out-of-bounds read, wild dereference and resulting oops are all confined to the host kernel\u0027s own security authority. No IOMMU, hypervisor, or sandbox boundary is crossed by the defect itself.\nC:H - tls_get_ctx() reads 8 bytes at offset 1264 of a 1152-byte unix_sock \u2014 a genuine out-of-bounds read into an adjacent, heap-groomable slab object \u2014 and the resulting value is then dereferenced at +0x30, yielding an arbitrary-address read whose outcome steers control flow as an observable oracle.\nI:H - This is a type confusion (vsock_sock/unix_sock treated as inet_connection_sock), which per scoring guidance carries High integrity impact; concretely, a spuriously \"true\" tls_sw_has_ctx_rx() in sk_skb_adjust_room() writes rxm-\u003efull_len += len_diff into the skb control block, corrupting strparser length bookkeeping on a socket that has no TLS context.\nA:H - The demonstrated result is an unhandled kernel page fault (\"BUG: unable to handle page fault for address: 0000000000040030\") inside a workqueue/softirq context, i.e. an oops that panics with panic_on_oops and otherwise kills the worker while holding sk_callback_lock and the socket lock, hanging the subsystem."

Detection rules are retrieved from Rulezet.

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.
