CVE-2021-46102

Exploit
From version 0.2.14 to 0.2.16 for Solana rBPF, function "relocate" in the file src/elf.rs has an integer overflow bug because the sym.st_value is read directly from ELF file without checking. If the sym.st_value is rather large, an integer overflow is triggered while calculating the variable "addr" via "addr = (sym.st_value + refd_pa) as u64";

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.
