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
In da, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09291294; Issue ID: MSV-2061.

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 missing bounds check in component 'da' allows an out-of-bounds write, enabling local privilege escalation. Exploitation requires physical access to the device and user interaction, but no additional execution privileges are needed.

MitigationApply patch ALPS09291294 and restrict physical access to the device until the update is deployed.

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 the exact product and OS version
    Run 'cat /etc/os-release' on Linux-based systems, or check 'ro.build.version.release' via 'getprop' on Android. For RDK, check the firmware version via 'cat /version.txt' or vendor documentation.
    Affected if The OS version matches one of the affected ranges: Yocto 4.0, RDK 2022q3 or 2024q1, Android 13.0/14.0/15.0, or OpenWRT 21.02.0/23.05
  2. Locate the 'da' component
    Search for any executable, library, or service named 'da' or containing 'da' in the name within common binary directories: 'find /usr/sbin /usr/bin /sbin /bin -name "*da*" 2>/dev/null' and check running processes with 'ps aux | grep -i da'.
    Affected if A component named 'da' exists on the system, as this is the vulnerable component referenced in the CVE.
  3. Verify the device has exposed physical access
    Assess whether the device is in a physically accessible location (e.g., unattended public areas, unlocked racks, or devices without tamper-evident hardware). Document the physical security controls in place.
    Affected if Physical access to the device is possible for an attacker, as exploitation requires physical access and user interaction.
  4. Check for user interaction requirements
    Determine if the device has user-facing interfaces (console, UI, buttons) that could be manipulated during physical access. Identify if users have authenticated sessions that could be interrupted or exploited.
    Affected if User interaction is possible during physical access, as the CVE states exploitation requires both physical access and user interaction.

You are affected if your device runs any of the listed OS versions AND contains the 'da' component AND is physically accessible to an attacker who can induce user interaction.
