CVE-2026-34069 nimiq-consensus panics via RequestMacroChain micro-block locator

nimiq/core-rs-albatross is a Rust implementation of the Nimiq Proof-of-Stake protocol based on the Albatross consensus algorithm. In versions 1.2.2 and below, an unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic. Sending a RequestMacroChain message where the...

CVE-2026-32605 Nimiq: Remote crash via off-by-one signer bounds check in proposal buffer

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, an untrusted peer could crash a validator by publishing a signed tendermint proposal message where signer == validators.numvalidators...

CVE-2026-31420

A flaw was found in the Linux kernel's bridge subsystem, specifically within the Multiple Registration Protocol MRP implementation. A local user can exploit this vulnerability by supplying a zero-value test interval through the netlink interface without proper validation. This invalid input cause...

CVE-2026-31424

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the xtables and arptables components. This vulnerability arises when xtmatch and xttarget extensions, registered for unspecified protocol families, are incorrectly processed by the Address Resolution Protocol ARP...

CVE-2026-31415

A flaw was found in the Linux kernel. A local attacker can exploit an integer overflow vulnerability in the ip6datagramsendctl function when processing multiple IPv6 Destination Options DSTOPTS control messages. This issue causes an incorrect calculation of header sizes, leading to a buffer...

nimiq-consensus panics via RequestMacroChain micro-block locator

Impact An unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic by sending a RequestMacroChain message where the first locator hash that is on the victim’s main chain is a micro block hash not a macro block hash. In RequestMacroChain::handle, the handler selects t...
