CVE-2026-64334
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: digi_acceleport: fix hard lockup on disconnect
If submitting the OOB write urb fails persistently (e.g if the device is
being disconnected) the driver would loop indefinitely with interrupts
disabled.
Check for urb submission errors when sending OOB commands to avoid
hanging if, for example, open(), set_termios() or close() races with a
physical disconnect.
This is issue was flagged by Sashiko when reviewing an unrelated change
to the driver.
