"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf, sockmap: Fix memleak in tcp_bpf_sendmsg while sk msg is full\n\nIf tcp_bpf_sendmsg() is running while sk msg is full. When sk_msg_alloc()\nreturns -ENOMEM error, tcp_bpf_sendmsg() goes to wait_for_memory. If partial\nmemory has been alloced by sk_msg_alloc(), that is, msg_tx->sg.size is\ngreater than osize after sk_msg_alloc(), memleak occurs. To fix we use\nsk_msg_trim() to release the allocated memory, then goto wait for memory.\n\nOther call paths of sk_msg_alloc() have the similar issue, such as\ntls_sw_sendmsg(), so handle sk_msg_trim logic inside sk_msg_alloc(),\nas Cong Wang suggested.\n\nThis issue can cause the following info:\nWARNING: CPU: 3 PID: 7950 at net/core/stream.c:208 sk_stream_kill_queues+0xd4/0x1a0\nCall Trace:\n <TASK>\n inet_csk_destroy_sock+0x55/0x110\n __tcp_close+0x279/0x470\n tcp_close+0x1f/0x60\n inet_release+0x3f/0x80\n __sock_release+0x3d/0xb0\n sock_close+0x11/0x20\n __fput+0x92/0x250\n task_work_run+0x6a/0xa0\n do_exit+0x33b/0xb60\n do_group_exit+0x2f/0xa0\n get_signal+0xb6/0x950\n arch_do_signal_or_restart+0xac/0x2a0\n exit_to_user_mode_prepare+0xa9/0x200\n syscall_exit_to_user_mode+0x12/0x30\n do_syscall_64+0x46/0x80\n entry_SYSCALL_64_after_hwframe+0x44/0xae\n </TASK>\n\nWARNING: CPU: 3 PID: 2094 at net/ipv4/af_inet.c:155 inet_sock_destruct+0x13c/0x260\nCall Trace:\n <TASK>\n __sk_destruct+0x24/0x1f0\n sk_psock_destroy+0x19b/0x1c0\n process_one_work+0x1b3/0x3c0\n kthread+0xe6/0x110\n ret_from_fork+0x22/0x30\n </TASK>"
