commit 2934325f56150ad8dab8ab92cbe2997242831396 upstream.

The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after
a cold boot.

A quirk already exists for "ZenBook UX425", but some Zenbooks report
"Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive,
the existing quirk is not applied to these "extra special" Zenbooks.

Testing confirms that this model needs the same quirks as the ZenBook
UX425 variants.

In the pegasus_notetaker driver, the pegasus_probe() function allocates the URB transfer buffer using the wMaxPacketSize value from the endpoint descriptor. An attacker can use a malicious USB descriptor to force the allocation of a very small buffer. Subsequently, if the device sends an interrupt packet with a specific pattern (e.g., where the first byte is 0x80 or 0x42), the pegasus_parse_packet() function parses the packet without checking the allocated buffer size.
