CVE-2024-30253Network attack vector

Application crash via unchecked deserialization bounds

Published Apr 17, 2024 · Updated Aug 21, 2024

Denial of service in Solana Web3.js allows remote attackers to crash applications that deserialize crafted transaction data. Message and transaction deserializers trust encoded element counts and continue shifting or splicing beyond the supplied byte array, exhausting memory instead of rejecting a truncated buffer. Exploitation requires an application to pass attacker-controlled serialized data to an affected SDK release; the documented consequence is process termination and service interruption.
