CVE-2023-53582 in Linux
Resumen
por VulDB • 2026-05-16
Based on the kernel stack trace provided, here is an analysis of the issue:
### **Summary** The system is attempting to **probe/bind a USB device driver** (specifically a USB interface driver). The process is stuck or crashing during the `usb_probe_interface` call, which is invoked as part of the standard USB device enumeration and driver binding process.
---
### **Key Observations from the Stack Trace**
1. **Context**: - The trace shows the kernel's device driver model attempting to attach a driver to a USB device. - The call chain starts from `usb_generic_driver_probe` → `usb_probe_device` → `really_probe` → `__driver_probe_device` → `driver_probe_device` → `__device_attach_driver` → ... → `usb_probe_interface`.
2. **Critical Function**: - `usb_probe_interface+0x25f/0x710`: This is where the actual USB interface driver's `probe()` function is called. This is the most likely location of the bug or hang. - The offset `+0x25f` suggests the crash/hang occurs early in the probe function.
3. **Process/Thread**: - `[ T1896]`: The operation is being performed by thread/task ID 1896. This is likely a kernel worker thread (e.g., `kworker` or `usb-storage` related) handling USB device insertion/configuration.
4. **Timing**: - `[ 33.035833]`: The event occurred 33 seconds after boot (or since the last log reset). This suggests it might be related to a device plugged in shortly after boot, or a delayed enumeration.
5. **Truncated**: - The trace is truncated (`---truncated---`), so we don't see the full context of what happened before or after. However, the presence of `usb_probe_interface` strongly indicates the issue is in the **USB interface driver's probe routine**.
---
### **Possible Causes**
1. **Driver Bug**: - The USB interface driver being probed has a bug in its `probe()` function (e.g., null pointer dereference, invalid memory access, infinite loop, or waiting on a resource that never becomes available).
2. **Hardware Issue**: - The USB device itself may be faulty, sending malformed descriptors, or causing the host controller to hang during configuration.
3. **Resource Conflict**: - The driver may be trying to acquire a resource (e.g., IRQ, DMA channel, memory-mapped I/O) that is already in use or unavailable.
4. **Timeout**: - The probe function may be waiting for a response from the device that never arrives, causing a hang (if not properly timed out).
5. **Kernel Bug**: - Less likely, but possible: a bug in the USB core (`usb_probe_interface`) or the driver model (`really_probe`).

### **How to Debug Further**
1. **Check Full Kernel Logs**: - Look for earlier messages from the same thread or related USB devices: ```bash dmesg | grep -i usb dmesg | grep -i "T1896" ``` - Look for any `BUG:`, `Oops`, `Call Trace`, or `WARNING` messages around the same timestamp.
2. **Identify the USB Device**: - Find out which USB device is being probed: ```bash lsusb dmesg | grep -i "new USB device" ``` - Check if the device is known to have issues.
3. **Identify the Driver**: - Determine which driver is being loaded for the USB interface: ```bash lsmod | grep -i usb dmesg | grep -i "bind driver" ``` - Common culprits: `usb-storage`, `cdc_ether`, `ftdi_sio`, `ch341`, `cp210x`, etc.
4. **Enable USB Debugging**: - Reboot with kernel parameters to enable verbose USB logging: ```bash usbcore.usb_debug=1 ``` - Or enable dynamic debugging for USB drivers: ```bash echo "file drivers/usb/core/*.c +p" > /sys/kernel/debug/dynamic_debug/control ```
5. **Check for Known Issues**: - Search for the specific USB device ID and driver combination for known bugs.
6. **Test with Different Hardware/Ports**: - Try a different USB port or cable to rule out hardware issues. - Try the device on another system
