  "description": "In the Linux kernel, the following vulnerability has been resolved:  tracing: Fix wild-memory-access in register_synth_event()  In register_synth_event(), if set_synth_event_print_fmt() failed, then both trace_remove_event_call() and unregister_trace_event() will be called, which means the trace_event_call will call __unregister_trace_event() twice. As the result, the second unregister will causes the wild-memory-access.  register_synth_event     set_synth_event_print_fmt failed     trace_remove_event_call         event_remove             if call-\u003Eevent.funcs then             __unregister_trace_event (first call)     unregister_trace_event         __unregister_trace_event (second call)  Fix the bug by avoiding to call the second __unregister_trace_event() by checking if the first one is called.  general protection fault, probably for non-canonical address \t0xfbd59c0000000024: 0000 [#1] SMP KASAN PTI KASAN: maybe wild-memory-access in range [0xdead000000000120-0xdead000000000127] CPU: 0 PID: 3807 Comm: modprobe Not tainted 6.1.0-rc1-00186-g76f33a7eedb4 #299 Hardware name: QEMU Standard PC (i440FX \u002B PIIX, 1996), BIOS rel-1.15.0-0-g2dd4b9b3f840-prebuilt.qemu.org 04/01/2014 RIP: 0010:unregister_trace_event\u002B0x6e/0x280 Code: 00 fc ff df 4c 89 ea 48 c1 ea 03 80 3c 02 00 0f 85 0e 02 00 00 48 b8 00 00 00 00 00 fc ff df 4c 8b 63 08 4c 89 e2 48 c1 ea 03 \u003C80\u003E 3c 02 00 0f 85 e2 01 00 00 49 89 2c 24 48 85 ed 74 28 e8 7a 9b RSP: 0018:ffff88810413f370 EFLAGS: 00010a06 RAX: dffffc0000000000 RBX: ffff888105d050b0 RCX: 0000000000000000 RDX: 1bd5a00000000024 RSI: ffff888119e276e0 RDI: ffffffff835a8b20 RBP: dead000000000100 R08: 0000000000000000 R09: fffffbfff0913481 R10: ffffffff8489a407 R11: fffffbfff0913480 R12: dead000000000122 R13: ffff888105d050b8 R14: 0000000000000000 R15: ffff888105d05028 FS:  00007f7823e8d540(0000) GS:ffff888119e00000(0000) knlGS:0000000000000000 CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f7823e7ebec CR3: 000000010a058002 CR4: 0000000000330ef0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace:  \u003CTASK\u003E  __create_synth_event\u002B0x1e37/0x1eb0  create_or_delete_synth_event\u002B0x110/0x250  synth_event_run_command\u002B0x2f/0x110  test_gen_synth_cmd\u002B0x170/0x2eb [synth_event_gen_test]  synth_event_gen_test_init\u002B0x76/0x9bc [synth_event_gen_test]  do_one_initcall\u002B0xdb/0x480  do_init_module\u002B0x1cf/0x680  load_module\u002B0x6a50/0x70a0  __do_sys_finit_module\u002B0x12f/0x1c0  do_syscall_64\u002B0x3f/0x90  entry_SYSCALL_64_after_hwframe\u002B0x63/0xcd",
