EEF-CVE-2026-59248 Unbounded HPACK/QPACK prefixed-integer decoding in Cowlib causes memory-exhaustion DoS

Summary Allocation of resources without limits vulnerability in ninenines cowlib allows an unauthenticated remote HTTP/2 or HTTP/3 peer to exhaust memory on the vulnerable server or client and cause a denial of service. The HPACK and QPACK prefixed-integer decoder cow\hpack\common:dec\big\int/3 i...

CVE-2026-63891

A flaw was found in the Linux kernel's Thunderbolt property parsing. An untrusted Thunderbolt peer, such as a cable or dock, can send specially crafted property requests that create a recursive loop. This can lead to kernel stack exhaustion, resulting in a system crash and a Denial of Service DoS...

In the Linux kernel, the following vulnerability has been resolved: thunderbolt: property: Cap recursion depth in tbpropertyparsedir A DIRECTORY entry's value field is used as the diroffset for a recursive call into tbpropertyparsedir with no depth counter. A crafted peer that chains DIRECTORY...

CVE-2026-44505 Nimiq network-libp2p: Untrusted peer can wedge DHT

Nimiq is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. network-libp2p handles kad get-record query progress in handledhtget network-libp2p/src/swarm.rs. Prior to version 1.4.0, when a peer returns a FoundRecord, the code verifies the record...

CVE-2026-44505

The CVE affects Nimiq’s network-libp2p component (Rust) used in the Albatross-based PoS implementation. Before v1.4.0, when a peer returns a FoundRecord, the code verified the record via dht_verifier.verify and, on verifier error, logged and returned early without completing the oneshot used by N...

CVE-2026-34065

CVE-2026-34065 affects nimiq-primitives in Nimiq’s Rust implementation. Before version 1.3.0, an untrusted p2p peer could cause a node to panic by announcing an election macro block whose validators set includes an invalid compressed BLS voting key. Hashing the election macro header hashes the va...

CVE-2026-34065

nimiq-primitives contains primitives e.g., block, account, transaction to be used in Nimiq's Rust implementation. Prior to version 1.3.0, an untrusted p2p peer can cause a node to panic by announcing an election macro block whose validators set contains an invalid compressed BLS voting key. Hashi...
