Therefore, ep is disabled before  \ngserial_disconnect sets port to null to prevent this from happening.  \n  \nCall trace:  \n gs_read_complete+0x58/0x240  \n usb_gadget_giveback_request+0x40/0x160  \n dwc3_remove_requests+0x170/0x484  \n dwc3_ep0_out_start+0xb0/0x1d4  \n __dwc3_gadget_start+0x25c/0x720  \n kretprobe_trampoline.cfi_jt+0x0/0x8  \n kretprobe_trampoline.cfi_jt+0x0/0x8  \n udc_bind_to_driver+0x1d8/0x300  \n usb_gadget_probe_driver+0xa8/0x1dc  \n gadget_dev_desc_UDC_store+0x13c/0x188  \n configfs_write_iter+0x160/0x1f4  \n vfs_write+0x2d0/0x40c  \n ksys_write+0x7c/0xf0  \n __arm64_sys_write+0x20/0x30  \n invoke_syscall+0x60/0x150  \n el0_svc_common+0x8c/0xf8  \n do_el0_svc+0x28/0xa0  \n el0_svc+0x24/0x84 \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"19 Jan 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-01-19T13:58:39.000000Z"}
