Kerentanan Integer Overflow or Wraparound pada solanalabs rbpf. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

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";
