Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： usb: core: hcd：修复 rh 控制传输中可能出现的死锁问题 在 SCSI 错误处理程序上下文中，内存分配不得触发 I/O 操作。处理 UAS（USB Attached SCSI）和存储驱动程序中的错误可能涉及设备重置。执行重置的线程本身依赖于 VM（虚拟内存）机制的支持。然而，这并不充分，因为重置设备需要将其恢复运行（resume）。恢复和重置操作都涉及向待重置设备的父设备（可能是根集线器）发送控制传输。因此，usbcore 必须正确处理通过 usb_submi

Vulnerability Title
usb: core: hcd: fix possible deadlock in rh control transfers
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
usb: core: hcd: fix possible deadlock in rh control transfers
>From within the SCSI error handler memory allocations must not
trigger IO. Handling errors in UAS and the storage driver may
involve resetting a device. The thread doing the reset itself
relies on VM magic. However, that is insufficient, as resetting
a device involves resuming it. Resumption as well as resetting
involves conrol transfers to the parent of the device to be reset.
That may be a root hub. Hence usbcore must heed the flags passed
to usb_submit_urb() processing control transfers to root hubs.
The problem exist since the storage driver has been merged.
