DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

can: gs_usb: gs_usb_receive_bulk_callback(): fix error message

Sinc commit 79a6d1bfe114 ("can: gs_usb: gs_usb_receive_bulk_callback(): unanchor URL on usb_submit_urb() error") a failing resubmit URB will print an info message.

In the case of a short read where netdev has not yet been assigned, initialize as NULL to avoid dereferencing an undefined value. Also report the error value of the failed resubmit.

AnalysisAI

A null pointer dereference in the Linux kernel's gs_usb driver can cause a denial of service when processing malformed USB bulk transfer callbacks, affecting systems with vulnerable CAN interface hardware. Local attackers with unprivileged access can trigger this crash by submitting crafted USB requests that fail resubmission. No patch is currently available for this vulnerability.
