      "title": "bpf, skmsg: fix verdict sk_data_ready racing with ktls rx",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, skmsg: fix verdict sk_data_ready racing with ktls rx\n\nsk_psock_strp_data_ready() already checks tls_sw_has_ctx_rx() and\ndefers to psock->saved_data_ready when a TLS RX context is present,\navoiding a conflict with the TLS strparser's ownership of the receive\nqueue (commit e91de6afa81c, \"bpf: Fix running sk_skb program types\nwith ktls\").\n\nsk_psock_verdict_data_ready() has no equivalent guard.  When a socket\nis inserted into a sockmap (BPF_SK_SKB_VERDICT) before TLS RX is\nconfigured, tls_sw_strparser_arm() saves sk_psock_verdict_data_ready\nas rx_ctx->saved_data_ready.  On data arrival:\n\n  tls_data_ready -> tls_strp_data_ready -> tls_rx_msg_ready\n    -> saved_data_ready() = sk_psock_verdict_data_ready()\n      -> tcp_read_skb() drains sk_receive_queue via __skb_unlink()\n         without calling tcp_eat_skb(), so copied_seq is not advanced.\n\ntls_strp_msg_load() then finds tcp_inq() >= full_len (stale), calls\ntcp_recv_skb() on the now-empty queue, hits WARN_ON_ONCE(!first), and\nreturns with rx_ctx->strp.anchor.frag_list pointing at a psock-owned\n(potentially freed) skb.  tls_decrypt_sg() subsequently walks that\nfrag_list: use-after-free.\n\nApply the same fix as sk_psock_strp_data_ready(): if a TLS RX context\nis present, call psock->saved_data_ready (sock_def_readable) to wake\nrecv() waiters and return immediately, leaving the receive queue\nuntouched.  TLS retains sole ownership of the queue and decrypts the\nrecord normally through tls_sw_recvmsg().",
