CVE-2026-33184— core-rs-albatross 数字错误漏洞

nimiq/core-rs-albatross: Discovery handshake limit could underflow and later provoke a deterministic overflow panic

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. Prior to version 1.3.0, the discovery handler accepts a peer-controlled limit during handshake and stores it unchanged. The immediate HandshakeAck path then honors limit = 0 and returns zero contacts, which makes the session look benign. Later, after the same session reaches Established, the periodic update path computes self.peer_list_limit.unwrap() as usize - 1. With limit = 0, that wraps to usize::MAX and then in rand 0.9.2, choose_multiple() immediately attempts Vec::with_capacity(amount), which deterministically panics with capacity overflow. This issue has been patched in version 1.3.0.

core-rs-albatross 数字错误漏洞

core-rs-albatross是Nimiq开源的一个Albatross协议的Rust实现。 core-rs-albatross 1.3.0之前版本存在数字错误漏洞，该漏洞源于发现处理程序接受对等控制限制且未更改存储，可能导致容量溢出和内核崩溃。
