Process crash via overflowing ELF memory range
Published May 21, 2022 · Updated Aug 3, 2024
Integer overflow in Solana solana_rbpf before 0.2.29 allows remote attackers to crash an ELF-loading process with a malformed eBPF ELF. During ELF loading, src/elf.rs accepts attacker-controlled p_vaddr and p_memsz values whose addition in goblin’s vm_range exceeds usize and triggers a checked-add panic. Applications that load attacker-supplied eBPF objects expose the path; the demonstrated consequence is a loader panic, not data disclosure or modification.
