CVE-2024-0093

What it actually does

The vulnerability allows a local, low-privileged process to read sensitive information from NVIDIA GPU software memory regions that should remain inaccessible.

Why it matters to the business

Organizations running affected NVIDIA GPU software on Linux may face leakage of confidential data such as cryptographic material or customer information, increasing regulatory and reputational risk.

How an attack unfolds

An attacker with local access on a Linux system using vulnerable NVIDIA GPU software reads protected memory regions via the flaw, obtaining information that was not intended for disclosure.

How to fix it

Apply the latest NVIDIA GPU software updates for all affected products including vGPU, Ubuntu, Citrix Hypervisor, RHEL KVM, VMware vSphere, and Cloud Gaming as soon as vendor patches become available; restrict local access where possible until updates are deployed.

How to confirm the fix worked

Verify that updated NVIDIA GPU driver and software packages are installed on all systems, confirm the vulnerable code paths are no longer present via package version checks, and retest local information disclosure scenarios in a lab environment.

Typical attack path

1. Obtain local shell or process execution on an affected Linux host
2. Identify presence of vulnerable NVIDIA GPU software components
3. Trigger the information disclosure path to dump protected memory
4. Exfiltrate captured sensitive data for further use or sale

How to detect it

Review local process execution logs and system call traces for unexpected reads of NVIDIA GPU device memory or driver buffers on affected hosts; correlate with authentication events showing low-privileged accounts accessing GPU resources.

What your security team should do

• Prioritize patching NVIDIA GPU software across all Linux-based virtualization and cloud gaming deployments
• Limit local user privileges on GPU hosts until patches are applied
• Monitor vendor security advisories for the release of fixed versions
• Review data exposure impact if GPU workloads handle sensitive information
