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).\n\nHowever, 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().\n\nFix the memory leak by anchoring the URB in the\ngs_usb_receive_bulk_callback() to the parent->rx_submitted anchor.","published":"2026-01-31T12:16:06.000Z","lastModified":"2026-06-17T10:20:45.000Z","status":"Deferred","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00224,"percentile":0.1288,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
