CVE-2024-1633

During the secure boot, bl2 (the second stage of
the bootloader) loops over images defined in the table “bl2_mem_params_descs”.
For each image, the bl2 reads the image length and destination from the image’s
certificate. Because of the way of reading from the image, which base on 32-bit unsigned integer value, it can result to an integer overflow. An attacker can bypass memory range restriction and write data out of buffer bounds, which could result in bypass of secure boot.

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.
