If the timer callback (command_timer_fn) is already\nrunning when lbtf_free_cmd_buffer() frees the command array, the\ncallback dereferences priv->cur_cmd->cmdbuf which points to freed\nmemory.\n\nSwap the order so that timer_delete_sync() runs first, ensuring any\nin-flight callback has completed before the command buffers are freed.","state":0,"publishedAt":"2026-10-06T08:44:34.253+00:00","modifiedAt":"2026-10-19T09:15:25.503+00:00","affected":[{"ecosystem":"Vendor
