Sleep Reveals the Nonce: Breaking ECDSA Using Sleep-Based Power Side-Channel Vulnerability

Security of Elliptic Curve Digital Signature Algorithm ECDSA depends on the secrecy of the per-signature nonce. Even partial nonce leakage can expose the long-term private key through lattice-based cryptanalysis. In this paper, we introduce a previously unexplored power side-channel vulnerability...

PIDSMaker: Building and Evaluating Provenance-Based Intrusion Detection Systems

Recent provenance-based intrusion detection systems PIDSs have demonstrated strong potential for detecting advanced persistent threats APTs by applying machine learning to system provenance graphs. However, evaluating and comparing PIDSs remains difficult: prior work uses inconsistent preprocessi...

CVE-2026-23553 x86: incomplete IBPB for vCPU isolation

In the context switch logic Xen attempts to skip an IBPB in the case of a vCPU returning to a CPU on which it was the previous vCPU to run. While safe for Xen's isolation between vCPUs, this prevents the guest kernel correctly isolating between tasks. Consider: 1 vCPU runs on CPU A, running task ...

CVE-2025-58150 x86: buffer overrun with shadow paging + tracing

Shadow mode tracing code uses a set of per-CPU variables to avoid cumbersome parameter passing. Some of these variables are written to with guest controlled data, of guest controllable size. That size can be larger than the variable, and bounding of the writes was missing...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005011 advisory. In the Linux kernel, the following vulnerability has been resolved: crypto: s390/aes - Fix buffer overread in CTR mode When processing the last block, the s390 ctr...

kernel: ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping

A flaw was found in the Linux kernel’s ASoC Intel bytcrrt5640 driver. When an invalid value is passed via the driver’s “quirk” input option, the driver merely logs an error and retains the invalid value, rather than correcting it. This can result in out-of-bounds OOB memory access...
