Описание
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.

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.
A flaw was found in the Linux kernel's `digi_acceleport` USB serial driver. This vulnerability occurs when a USB device using the driver is disconnected, and operations such as opening or closing the device are happening concurrently. Persistent errors in sending out-of-band (OOB) write Universal Serial Bus Request Blocks (URBs) can cause the driver to enter an indefinite loop with interrupts disabled. This leads to a system hard lockup, resulting in a Denial of Service (DoS).
