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
Memory corruption may occour while generating test pattern due to negative indexing of display ID.

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 memory corruption vulnerability exists in the test pattern generation functionality where a display ID is used as an array index without proper validation. When a negative value is provided as the display ID, it results in negative indexing which causes the code to access memory outside the intended buffer bounds, leading to memory corruption.

MitigationImplement proper input validation to ensure display IDs are non-negative and within valid bounds before use as array indices; also add bounds checking in the test pattern generation code to prevent out-of-bounds memory access.

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 Qualcomm platform firmware version
    Check system information or firmware metadata to determine if the device runs any of the affected Qualcomm platforms: Fastconnect 6700/6900/7800, Qcm5430/Qcm6490, Qcs5430/Qcs6490, or Video Collaboration Vc3 Platform. Consult the device firmware version via vendor utilities, bootloader information, or system logs.
    Affected if The device uses any of the listed Qualcomm platform firmware versions (all versions are affected)
  2. Locate the test pattern generation functionality
    Search firmware binaries or driver code for test pattern generation functions that accept display ID as a parameter. This may appear in debug/test utilities, graphics driver code, or display subsystem modules.
    Affected if Test pattern generation code that uses display IDs as array indices exists in the firmware
  3. Verify display ID input validation exists
    Examine the test pattern generation code path to check whether display ID values are validated before being used as array indices. Look for bounds checking, sign validation, or range limits on the display ID parameter.
    Affected if No validation or bounds checking is performed on display ID before array indexing, allowing negative values to pass through
  4. Check for exploitation indicators
    Review system crash logs, memory dumps, or kernel panic logs for patterns indicating memory corruption triggered by negative array indexing. Look for crashes occurring during or after display-related test operations.
    Affected if Memory corruption or unexpected crashes correlate with display test pattern operations

If the environment uses any version of the affected Qualcomm platforms and contains the test pattern generation feature without proper display ID validation, the system is vulnerable to this negative indexing flaw.

Mitigation

Implement proper input validation to ensure display IDs are non-negative and within valid bounds before use as array indices; also add bounds checking in the test pattern generation code to prevent out-of-bounds memory access.
