CVE ID : CVE-2026-23031<\/p>\n

Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak<\/p>\n
In gs_can_open(), the URBs for USB-in transfers are allocated, added to the
\nparent->rx_submitted anchor and submitted. In the complete callback
\ngs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In
\ngs_can_close() the URBs are freed by calling
\nusb_kill_anchored_urbs(parent->rx_submitted).<\/p>\n
However, this does not take into account that the USB framework unanchors
\nthe URB before the complete function is called. This means that once an
\nin-URB has been completed, it is no longer anchored and is ultimately not
\nreleased in gs_can_close().<\/p>\n
Fix the memory leak by anchoring the URB in the
\ngs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.<\/p>\n
Severity: 0.0 | NA<\/p>\n
