Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Software installed and run as a non-privileged user may conduct improper GPU system calls to achieve unauthorised reads and writes of physical memory from the GPU HW.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A vulnerability in GPU system call handling allows non-privileged user-space software to make improper GPU system calls that bypass memory access controls, enabling unauthorized reads and writes of physical system memory directly from GPU hardware.

MitigationApply vendor-provided GPU driver and firmware updates that enforce proper privilege separation and memory access validation for GPU system calls; consider GPU passthrough virtualization with strict access controls until patched.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify GPU hardware present
    Run 'lspci | grep -i vga' or 'lspci | grep -i display' on Linux, or check Device Manager on Windows to list installed GPU devices
    Affected if The system has a discrete or integrated GPU from any major vendor (NVIDIA, AMD, Intel, etc.)
  2. Determine GPU driver version
    On Linux: 'nvidia-smi' for NVIDIA, 'lsmod | grep amdgpu' or 'cat /sys/class/drm/card*/device/driver_version' for AMD, 'cat /sys/class/drm/card*/device/driver' for Intel. On Windows: Check driver details in Device Manager under the GPU properties
    Affected if The driver version cannot be determined or is older than vendor-specific security patches for this vulnerability
  3. Check for GPU security advisories
    Search GPU vendor security bulletins (NVIDIA Security Bulletin, AMD Security Advisory, Intel Security Center) using the CVE number or keywords about GPU memory access control
    Affected if The installed driver version falls within an affected range listed in vendor security advisories for CVE-2024-43703 or similar GPU privilege bypass issues
  4. Verify GPU memory access controls
    Check if GPU Direct Memory Access (DMA) or GPU passthrough features are enabled: On Linux, check 'dmesg' for GPU-related messages, review /etc/modprobe.conf for GPU module parameters, or check virtualization settings if using GPU passthrough
    Affected if GPU DMA, passthrough, or direct memory mapping features are enabled and the driver lacks proper privilege validation for GPU system calls
  5. Review GPU system call permissions
    Monitor system for GPU-related system calls using audit rules ('auditctl -w /dev/nvidia* -p rwxa' for NVIDIA, or similar for AMD/Intel), or check /proc/driver/*/version files
    Affected if Non-privileged processes can access GPU device files (/dev/nvidia*, /dev/dri/*) without additional restrictions and the driver does not validate call privileges

If the system has a GPU with a driver version that lacks vendor security updates for CVE-2024-43703, the environment is affected by this privilege bypass vulnerability.
