CVE-2026-34063

Nimiq's network-libp2p is a Nimiq network implementation based on libp2p. Prior to version 1.3.0, network-libp2p discovery uses a libp2p ConnectionHandler state machine. the handler assumes there is at most one inbound and one outbound discovery substream per connection. if a remote peer...

CVE-2026-31518

A flaw was found in the Linux kernel. When the espintcp component processes network traffic using asynchronous cryptography, a memory leak can occur. This happens because a socket buffer skb is not correctly released if the transmit queue becomes full. This continuous leak of memory can lead to...

CVE-2026-34066 nimiq-blockchain: Peer-triggerable panic during history sync

nimiq-blockchain provides persistent block storage for Nimiq's Rust implementation. Prior to version 1.3.0, HistoryStore::puthistorictxns uses an assert! to enforce invariants about HistoricTransaction.blocknumber must be within the macro block being pushed and within the same epoch. During histo...

CVE-2026-31504

A flaw was found in the Linux kernel. A race condition in the packetrelease function, specifically during a network device up NETDEVUP event, can lead to a Use-After-Free UAF vulnerability. This occurs when a socket is re-registered into a fanout group's array, leaving a dangling pointer. A local...

CVE-2026-31454

A flaw was found in the Linux kernel's XFS file system. This vulnerability occurs when the system incorrectly handles memory, specifically when a critical lock, known as the Address Index List AIL lock, is released too early during certain operations. This premature release can cause a piece of...
