| Subject: CVE-2025-22051: staging: gpib: Fix Oops after disconnect in agilent usb |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| staging: gpib: Fix Oops after disconnect in agilent usb |
| |
| If the agilent usb dongle is disconnected subsequent calls to the |
| driver cause a NULL dereference Oops as the bus_interface |
| is set to NULL on disconnect. |
| |
| This problem was introduced by setting usb_dev from the bus_interface |
| for dev_xxx messages. |
| |
| Previously bus_interface was checked for NULL only in the functions |
| directly calling usb_fill_bulk_urb or usb_control_msg. |
| |
| Check for valid bus_interface on all interface entry points |
| and return -ENODEV if it is NULL. |
| |
| The Linux kernel CVE team has assigned CVE-2025-22051 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/e88633705078f40391a9afc6cc8ea3025e6f692b |
