Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf, skmsg: fix verdict sk_data_ready
 racing with ktls rx sk_psock_strp_data_ready() already checks tls_sw_has_ctx_rx() and defers to
 psock->saved_data_ready when a TLS RX context is present, avoiding a conflict with the TLS strparser's
 ownership of the receive queue (commit e91de6afa81c, "bpf: Fix running sk_skb program types with ktls").
 sk_psock_verdict_data_ready() has no equivalent guard. When a socket is inserted into a sockmap
 (BPF_SK_SKB_VERDICT) before TLS RX is configured, tls_sw_strparser_arm() saves sk_psock_verdict_data_ready
 as rx_ctx->saved_data_ready. On data arrival: tls_data_ready -> tls_strp_data_ready -> tls_rx_msg_ready ->
 saved_data_ready() = sk_psock_verdict_data_ready() -> tcp_read_skb() drains sk_receive_queue via
 __skb_unlink() without calling tcp_eat_skb(), so copied_seq is not advanced. tls_strp_msg_load() then
 finds tcp_inq() >= full_len (stale), calls tcp_recv_skb() on the now-empty queue, hits
 WARN_ON_ONCE(!first), and returns with rx_ctx->strp.anchor.frag_list pointing at a psock-owned
 (potentially freed) skb. tls_decrypt_sg() subsequently walks that frag_list: use-after-free. Apply the
 same fix as sk_psock_strp_data_ready(): if a TLS RX context is present, call psock->saved_data_ready
 (sock_def_readable) to wake recv() waiters and return immediately, leaving the receive queue untouched.
 TLS retains sole ownership of the queue and decrypts the record normally through tls_sw_recvmsg().
 (CVE-2026-64025)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.2 or later.
