CVE-2024-30212

If a SCSI READ(10) command is initiated via USB using the largest LBA 
(0xFFFFFFFF) with it's default block size of 512 and a count of 1,

the first 512 byte of the 0x80000000 memory area is returned to the 
user. If the block count is increased, the full RAM can be exposed.

The same method works to write to this memory area. If RAM contains 
pointers, those can be - depending on the application - overwritten to

return data from any other offset including Progam and Boot Flash.

CWE-190 Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
