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 in Core while invoking a call to Access Control core library with hardware protected address range.

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

Memory corruption vulnerability in the Core component that occurs when invoking calls to the Access Control core library with hardware-protected address ranges. The flaw appears to involve improper handling of memory protection mechanisms during access control operations, potentially allowing privilege escalation or code execution.

MitigationApply vendor patches promptly; given the hardware-level interaction involved with protected address ranges, ensure firmware, system updates, and any associated microcode are also updated as part of remediation.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 affected Qualcomm components
    Inventory your systems for any of the following Qualcomm firmware or hardware: Ar8035, Fastconnect 6700, Fastconnect 6900, Fastconnect 7800, Qca8081, Qca8337, Qcm4490, or Qcm8550. Check device inventories, hardware manifests, or firmware dumps for these component identifiers.
    Affected if Any of these eight Qualcomm components are present in the environment
  2. Determine firmware version
    For each identified Qualcomm component, retrieve the installed firmware version using vendor-specific tools (e.g., 'cat /proc/version', 'dmesg', or chipset-specific diagnostic utilities). Compare the version against the affected product list.
    Affected if The component is any version of the listed Qualcomm firmware (all versions are affected)
  3. Verify Access Control library usage
    Examine system logs, application configurations, or firmware analysis for invocation of the Access Control core library functions, particularly those that interact with hardware-protected memory address ranges.
    Affected if The Access Control core library is being called with hardware-protected address ranges
  4. Monitor for memory corruption indicators
    Review system crash logs, kernel panics, or memory dump files for signs of memory corruption related to access control operations. Check for unexpected privilege escalation or code execution anomalies.
    Affected if Memory corruption events or unexpected privilege changes are observed in conjunction with Access Control operations

You are affected if your environment contains any of the eight listed Qualcomm firmware components (Ar8035, Fastconnect 6700/6900/7800, Qca8081, Qca8337, Qcm4490, Qcm8550) and utilizes the Access Control core library with hardware-protected address ranges.
