RUSTSEC-2021-0109Published

An issue was discovered in the ckb crate before 0.40.0 for Rust. Attackers can cause a denial of service (Nervos CKB blockchain node crash) via a dead call that is used as a DepGroup.

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.
