CVE-2021-46102: Solanalabs Rbpf

High severity, CVSS 7.5. EPSS: 1.9% chance of exploitation in the next 30 days.

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";

Affected products

• Solanalabs Rbpf: from 0.2.14, up to and including 0.2.16
