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
NVIDIA Jetson Linux and IGX OS contain a vulnerability in NvMap, where improper tracking of memory allocations could allow a local attacker to cause memory overallocation. A successful exploitation of this vulnerability might lead to denial of service.

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

NVIDIA Jetson Linux and IGX OS contain a vulnerability in NvMap, a memory management component. Improper tracking of memory allocations allows a local attacker to cause memory overallocation, potentially leading to denial of service through resource exhaustion.

MitigationApply NVIDIA-provided firmware/software updates for Jetson Linux and IGX OS that address the NvMap memory tracking issue. Restrict local access to trusted users to reduce attack surface.

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 system platform
    Run 'cat /etc/os-release' or check '/proc/device-tree/model' on the device to confirm it is NVIDIA Jetson or IGX OS
    Affected if System is not running Jetson Linux or IGX OS - this vulnerability only applies to these platforms
  2. Check installed software version
    Run 'dpkg -l | grep nvidia-l4t' or 'apt list --installed | grep nvidia' to obtain the NVIDIA Jetson Linux or IGX OS version number
    Affected if Version cannot be determined or is not documented in NVIDIA's official version listing for this CVE
  3. Verify NvMap component is present
    Check for NvMap kernel module with 'lsmod | grep nvmap' or look for '/dev/nvmap' device node with 'ls -l /dev/nvmap'
    Affected if NvMap component is not present on the system - the vulnerability only affects systems with this memory management component
  4. Check memory allocation state
    Monitor current memory allocation status via 'cat /proc/meminfo' or check NvMap-specific status if available through NVIDIA tools
    Affected if Memory is severely overallocated or system shows signs of resource exhaustion related to memory tracking issues

User is affected if running vulnerable versions of NVIDIA Jetson Linux or IGX OS with NvMap component active, where memory overallocation can be triggered locally.
