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 occurs during the copying of read data from the EEPROM because the IO configuration is exposed as shared memory.

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 is a memory corruption vulnerability in EEPROM read operations where IO configuration is incorrectly exposed as shared memory. When reading data from the EEPROM, the copying process can corrupt memory because the IO configuration (which should be protected) is accessible as shared memory, potentially allowing concurrent access or improper handling during the read operation.

MitigationFix the IO configuration handling to prevent exposure as shared memory and implement proper synchronization or memory protection mechanisms for EEPROM read operations to prevent corruption.

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 chipset model in the device
    Check the system hardware inventory, device firmware manifest, or kernel modules for the presence of Qca6391, Qca6426, Qca6436, Qca6574au, Qcn9074, Qcs410, or Qcs610 chipset identifiers. On Linux systems, this may appear in `lspci`, `dmesg`, or firmware dump files.
    Affected if The device contains any of the listed Qualcomm chipset models (Qca6391, Qca6426, Qca6436, Qca6574au, Qcn9074, Qcs410, Qcs610)
  2. Confirm the firmware version
    Retrieve the firmware version string from the affected Qualcomm component. This may be available via debug interfaces, firmware metadata files, or device system information. Look for firmware version strings in the EEPROM or firmware binary.
    Affected if Firmware version is present and matches the affected chipset models (all versions are affected)
  3. Verify EEPROM access functionality
    Check if the system performs EEPROM read operations. Review any logs, diagnostics, or system calls related to EEPROM data access. This may involve examining driver behavior or network subsystem logs for EEPROM read events.
    Affected if The system performs EEPROM reads using the affected firmware components

If the device implements any of the affected Qualcomm chipsets (Qca6391, Qca6426, Qca6436, Qca6574au, Qcn9074, Qcs410, Qcs610) and uses EEPROM read operations, the environment is affected because all firmware versions of these products contain the memory corruption vulnerability.
