CVE-2026-2681

A flaw was found in the blst cryptographic library. This out-of-bounds stack write vulnerability, specifically in the blstsha256bcopy assembly routine, occurs due to a missing zero-length guard. A remote attacker can exploit this by providing a zero-length salt parameter to key generation...

GHSA-4G52-PQCJ-PHVH BLS Signature "Malleability"

Impact 1. BLS signature validation in lotus uses blst library method VerifyCompressed. This method accepts signatures in 2 forms - "serialized", and "compressed", meaning that BLS signatures can be provided as either of 2 unique byte arrays. 2. Lotus block validation functions perform a uniquenes...
