Subject: CVE-2023-52655: usb: aqc111: check packet for fixup for true limit

Description
===========

In the Linux kernel, the following vulnerability has been resolved:

usb: aqc111: check packet for fixup for true limit

If a device sends a packet that is inbetween 0
and sizeof(u64) the value passed to skb_trim()
as length will wrap around ending up as some very
large value.

The driver will then proceed to parse the header
located at that position, which will either oops or
process some random value.

The fix is to check against sizeof(u64) rather than
0, which the driver currently does. The issue exists
since the introduction of the driver.

The Linux kernel CVE team has assigned CVE-2023-52655 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
