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
Information disclosure when ASLR relocates the IMEM and Secure DDR portions as one chunk in virtual address space.

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 allows information disclosure because Address Space Layout Randomization (ASLR) relocates the IMEM (Internal Memory) and Secure DDR (Secure Double Data Rate) regions as one contiguous chunk in virtual address space, rather than as independent random chunks. This enables attackers to potentially deduce memory layout and defeat ASLR protections.

MitigationThis requires a firmware update from the device vendor that modifies the ASLR implementation to randomize IMEM and Secure DDR as separate, independently relocated chunks in virtual address space.

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 chipset model
    Check the device or system information to determine if the chipset is one of the following: Fastconnect 6900, Fastconnect 7800, Qcm8550, Qcs8550, Sg8275p, Sm8550p, Snapdragon 8 Gen 2, or Snapdragon 8+ Gen 2
    Affected if The chipset matches any of the listed affected models
  2. Confirm firmware version
    Attempt to retrieve the firmware version from the device or system logs, typically accessible via diagnostic tools or by checking the wireless/wireless firmware subsystem
    Affected if The firmware version cannot be determined or is present on an affected chipset (all versions are affected)
  3. Inspect IMEM and Secure DDR memory layout
    Analyze the virtual memory mapping of the firmware, specifically examining the relative positions of IMEM (Internal Memory) and Secure DDR regions in the address space
    Affected if IMEM and Secure DDR regions appear as a single contiguous block rather than independently randomized separate chunks

If the device uses any of the listed Qualcomm chipsets with their firmware, the ASLR implementation is vulnerable because IMEM and Secure DDR are randomized as one contiguous chunk instead of independent chunks.

Mitigation

This requires a firmware update from the device vendor that modifies the ASLR implementation to randomize IMEM and Secure DDR as separate, independently relocated chunks in virtual address space.

Recommended fix Moderate confidence

Firmware version containing CVE-2024-21460 fix (check Qualcomm security bulletin for specific release)

  1. Check Qualcomm's security bulletins (docs.qualcomm.com) for CVE-2024-21460 to identify the specific firmware version containing the security fix
  2. Contact your device/original equipment manufacturer (OEM) to obtain the updated firmware that addresses this vulnerability
  3. Apply the firmware update following the OEM's standard update procedure
  4. Verify the ASLR implementation now properly randomizes IMEM and Secure DDR as separate chunks
Caveat Firmware updates may require device downtime and should be tested in a staging environment before production deployment
