"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Add NULL pointer check to trigger_data_free()\n\nIf trigger_data_alloc() fails and returns NULL, event_hist_trigger_parse()\njumps to the out_free error path. While kfree() safely handles a NULL\npointer, trigger_data_free() does not. This causes a NULL pointer\ndereference in trigger_data_free() when evaluating\ndata->cmd_ops->set_filter.\n\nFix the problem by adding a NULL pointer check to trigger_data_free().\n\nThe problem was found by an experimental code review agent based on\ngemini-3.1-pro while reviewing backports into v6.18.y."
