Flexible Hardware-Enabled Guarantees for AI Compute

As artificial intelligence systems become increasingly powerful, they pose growing risks to international security, creating urgent coordination challenges that current governance approaches struggle to address without compromising sensitive information or national security. We propose flexible...

Detecting Hardware Trojans in Microprocessors via Hardware Error Correction Code-based Modules

Software-exploitable Hardware Trojans HTs enable attackers to execute unauthorized software or gain illicit access to privileged operations. This manuscript introduces a hardware-based methodology for detecting runtime HT activations using Error Correction Codes ECCs on a RISC-V microprocessor...

Side-Channel Extraction of Dataflow AI Accelerator Hardware Parameters

Dataflow neural network accelerators efficiently process AI tasks on FPGAs, with deployment simplified by ready-to-use frameworks and pre-trained models. However, this convenience makes them vulnerable to malicious actors seeking to reverse engineer valuable Intellectual Property IP through...

Malware in mattermost-hardware-keyboard

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outsid...

SUSE CVE-2022-49945

In the Linux kernel, the following vulnerability has been resolved: hwmon: gpio-fan Fix array out of bounds access The driver does not check if the cooling state passed to gpiofansetcurstate exceeds the maximum cooling state as stored in fandata-numspeeds. Since the cooling state is later used as...

SUSE CVE-2022-50015

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot It is not yet clear, but it is possible to create a firmware so broken that it will send a reply message before a FWREADY message it is not yet clear if...

CVE-2022-50228

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Don't BUG if userspace injects an interrupt with GIF=0 Don't BUG/WARN on interrupt injection due to GIF being cleared, since it's trivial for userspace to force the situation via KVMSETVCPUEVENTS even if having at least...

CVE-2022-50186

In the Linux kernel, the following vulnerability has been resolved: ath11k: fix missing skb drop on htctxcompletion error On htctxcompletion error the skb is not dropped. This is wrong since the completionhandler logic expect the skb to be consumed anyway even when an error is triggered. Not...

CVE-2022-50187

In the Linux kernel, the following vulnerability has been resolved: ath11k: fix netdev open race Make sure to allocate resources needed before registering the device. This specifically avoids having a racing open trigger a BUGON in modtimer when ath11kmacopstart is called before the monreaptimer ...
