Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.5.0, a remote peer can crash any full node by sending a RequestBatchSet message containing the genesis block's hash. The handler calls getepochchunks which iterates...

CVE-2026-46540 Nimiq light-blockchain: Light blockchain rebranch issue

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.4.0, when LightBlockchain::rebranch adopts a fork chain whose tip is a macro block checkpoint or election, it only updates self.head but fails to update self.macrohea...

CVE-2026-46540

Nimiq light-blockchain (Rust, Albatross) had a bug in LightBlockchain::rebranch() before v1.4.0: when forking to a macro-block tip (checkpoint or election), it updated only head and did not refresh macro_head, election_head, current_validators, or store the election header. This mismatch with the...

CVE-2026-45782

Cloud Hypervisor (virtio-block) is affected from 21.0 up to before 51.2. The issue arises in asynchronous virtio-block I/O completion when two descriptor chains reuse the same head_index, allowing a use-after-free that corrupts a bounce buffer if the duplicate operation completes before the origi...
