USB: validate wMaxPacketValue entries in endpoint descriptors
Erroneous or malicious endpoint descriptors may have non-zero bits in
reserved positions, or out-of-bounds values. This patch helps prevent
these from causing problems by bounds-checking the wMaxPacketValue
entries in endpoint descriptors and capping the values at the maximum
allowed.
This issue was first discovered and tests were conducted by Jake Lamberson
<[email protected]>, an intern working for Rosie Hall.
