--- Comment #3 from Alan Stern (stern@rowland.harvard.edu) ---
The warnings about ene_ub6250.c are accurate. The driver uses (EntryOffset %
512) to index a 512-byte buffer and dereferences a 16-bit value at that
location, without checking for proper alignment. It then dereferences another
16-bit value located 10 bytes farther on, without checking for overflow.
Not having the specs for this type of device, I don't know how this is meant to
work. Perhaps EntryOffset % 512 is always supposed to be 0. But perhaps not,
so I don't want to make any hasty changes.
