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 when writing to invalid memory locations occurs due to heap memory exhaustion during secure data initialization.

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

This vulnerability involves heap memory exhaustion during secure data initialization, leading to memory corruption when the application attempts to write to invalid memory locations. The issue stems from inadequate memory management or bounds checking when handling secure data structures during initialization, potentially allowing an attacker to trigger out-of-bounds writes.

MitigationImplement proper memory allocation validation and bounds checking during secure data initialization to prevent heap exhaustion. Add error handling for memory allocation failures and ensure all memory writes are validated against allocated buffer sizes.

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 firmware component in your device
    Examine your device's system information, firmware metadata, or boot logs to determine which Qualcomm component is present (Cologne, Cq7790, Cq8725s, Cq8750m, Fastconnect 6200, Wsa8840, Wsa8845, or Wsa8845h)
    Affected if The device contains any of the listed Qualcomm firmware components (Cologne, Cq7790, Cq8725s, Cq8750m, Fastconnect 6200, Wsa8840, Wsa8845, or Wsa8845h)
  2. Verify the firmware version
    Check the installed firmware version using the device's CLI (e.g., 'version', 'show version', 'cat /proc/version' or vendor-specific commands) and compare against the affected product list
    Affected if The firmware version matches any of the affected products (all versions of Cologne, Cq7790, Cq8725s, Cq8750m, Fastconnect 6200, Wsa8840, Wsa8845, or Wsa8845h are affected)
  3. Confirm secure data initialization feature is active
    Review system configuration or debug logs for references to 'secure data initialization', 'secure boot', or memory allocation during the early boot sequence
    Affected if Secure data initialization is performed during device startup or firmware operation
  4. Check for heap exhaustion indicators
    Monitor system logs, dmesg, or device event logs for out-of-memory errors, allocation failures, or memory corruption messages occurring during initialization phases
    Affected if Heap allocation failures or memory corruption errors appear in system logs, particularly during boot or secure initialization
  5. Inspect for abnormal memory behavior
    Use memory diagnostic tools or firmware debug interfaces to look for unexpected memory writes, heap corruption markers, or buffer overflow signatures in the affected component's memory region
    Affected if Memory corruption, unexpected write attempts to invalid addresses, or heap metadata corruption is detected

A defender is affected if their device uses any of the listed Qualcomm firmware components (Cologne, Cq7790, Cq8725s, Cq8750m, Fastconnect 6200, Wsa8840, Wsa8845, or Wsa8845h) and performs secure data initialization, since all versions of these products contain the vulnerability.
