Bullshark on Narwhal: Implementation-Level Workflow Analysis of Round-Based DAG Consensus in Theory and Practice

Round-based DAGs enable high-performance Byzantine fault-tolerant consensus, yet their technical advantages remain underutilized due to their short history. While research on consensus protocols is active in both academia and industry, many studies overlook implementation-level algorithms, leavin...

Private Continual Counting of Unbounded Streams

We study the problem of differentially private continual counting in the unbounded setting where the input size $n$ is not known in advance. Current state-of-the-art algorithms based on optimal instantiations of the matrix mechanism cannot be directly applied here because their privacy guarantees...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: netem: Update sch-q.qlen before qdisctreereducebacklog. The qdisctreereducebacklog function only notifies the parent qdisc if the child qdisc becomes empty. Therefore, we need to reduce the backlog of the child qdisc before calli...

Oracle-Based Multistep Strategy for Solving Polynomial Systems over Finite Fields and Algebraic Cryptanalysis of the Aradi Cipher

The multistep solving strategy consists in a divide-and-conquer approach: when a multivariate polynomial system is computationally infeasible to solve directly, one variable is assigned over the elements of the base finite field, and the procedure is recursively applied to the resulting simplifie...

UBUNTU-CVE-2025-37915

In the Linux kernel, the following vulnerability has been resolved: netsched: drr: Fix double list add in class with netem as child qdisc As described in Gerrard's report 1, there are use cases where a netem child qdisc will make the parent qdisc's enqueue callback reentrant. In the case of drr,...

kernel: ACPI: PAD: fix crash in exit_round_robin()

In the Linux kernel, the following vulnerability has been resolved: ACPI: PAD: fix crash in exitroundrobin The kernel occasionally crashes in cpumaskclearcpu, which is called within exitroundrobin, because when executing clearbitnr, addr with nr set to 0xffffffff, the address calculation may caus...

Kudzu: Fast and Simple High-Throughput BFT

We present Kudzu, a high-throughput atomic broadcast protocol with an integrated fast path. Our contribution is based on the combination of two lines of work. Firstly, our protocol achieves finality in just two rounds of communication if all but $p$ out of $n = 3f + 2p + 1$ participating replicas...

A Cryptographic Perspective on Mitigation Vs. Detection in Machine Learning

In this paper, we initiate a cryptographically inspired theoretical study of detection versus mitigation of adversarial inputs produced by attackers of Machine Learning algorithms during inference time. We formally define defense by detection DbD and defense by mitigation DbM. Our definitions com...

The vulnerability of the exit_round_robin() function in the ACPI kernel of Linux operating systems allows a hacker to trigger a service failure.

The vulnerability of the exitroundrobin function in ACPI components of Linux operating systems is related to the round-robin scheduling algorithm. Exploiting this vulnerability could allow an attacker to trigger a service failure...

SUSE CVE-2025-21971

In the Linux kernel, the following vulnerability has been resolved: netsched: Prevent creation of classes with TCHROOT The function qdisctreereducebacklog uses TCHROOT as a termination condition when traversing up the qdisc tree to update parent backlog counters. However, if a class is created wi...
