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
Integer overflow within the AMD NPU Driver could allow a local attacker to write out of bounds, potentially leading to a loss of confidentiality, integrity, or availability.

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

Integer overflow vulnerability in AMD NPU (Neural Processing Unit) driver allows a local attacker to perform out-of-bounds memory writes. The flaw exists in memory allocation/calculation logic within the driver, where integer overflow causes incorrect buffer size calculations leading to writes beyond allocated memory boundaries.

MitigationApply AMD-provided driver updates for NPU hardware when released. Inventory systems with AMD NPU components and prioritize patching based on exposure. As a compensating control, restrict local access to trusted personnel only until official patches are available.

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 AMD NPU hardware presence
    Run 'lspci | grep -i neural' or check Device Manager under 'System devices' for AMD Neural Processing Unit, or run 'Get-PnpDevice -Class Processor -Status OK' on Windows and look for NPU entries
    Affected if System has AMD NPU hardware installed ( Ryzen AI, AMD XDNA NPU, or similar)
  2. Determine installed NPU driver version
    On Windows: open Device Manager, right-click the NPU device under 'System devices', select Properties > Driver tab, note the driver version. On Linux: run 'ls -la /dev/accel*' or check 'dmesg | grep -i npu' for driver load messages, or check '/sys/class/accel/accel*' for driver info
    Affected if NPU driver is present and version is known (vulnerable versions would be specific to AMD's advisory)
  3. Check for vulnerable memory allocation code path
    Inspect NPU driver files: on Windows check '%SystemRoot%\System32\drivers\amdnpu*.sys' file version and properties; on Linux check '/lib/modules/$(uname -r)/kernel/drivers/accel/amdnpu*' or similar driver paths
    Affected if Vulnerable driver binary exists with the integer overflow in memory calculation routines
  4. Verify local attacker context
    Review system user accounts and privileges with 'who' or 'net user' on Windows, check if untrusted local users exist with interactive logon rights; verify if NPU driver services run with elevated privileges
    Affected if Untrusted local users have access to the system (attacker needs local access to trigger the overflow)

System is affected if it contains AMD NPU hardware running an unpatched driver version where the integer overflow in memory allocation/calculation logic can be triggered by a local attacker.
