CVE-2020-11214
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 · uneditedBuffer over-read while processing NDL attribute if attribute length is larger than expected and then FW is treating it as more number of immutable schedules in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wired Infrastructure and Networking
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 confidenceA buffer over-read vulnerability exists in Qualcomm Snapdragon firmware when processing NDL attributes. If the attribute length exceeds expected values, the firmware incorrectly interprets the data as indicating a larger number of immutable schedules, causing it to read beyond buffer boundaries. This can potentially allow remote attackers to access sensitive memory contents or cause denial of service.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Qualcomm chip model in your deviceCheck device hardware specifications, or run commands like `lspci -v`, `cat /proc/cpuinfo`, or check the device manufacturer documentation to determine which Qualcomm chip is presentAffected if The chip model matches one of: Aqt1000, Ar8031, Ar8035, Csr8811, Csra6620, Csra6640, Csrb31024, or Ipq5010
-
Locate firmware version informationAccess the device firmware or admin interface, check manufacturer documentation, or use device-specific commands to retrieve the current firmware versionAffected if The firmware version cannot be confirmed as patched by the vendor or is running an older unreleased version
-
Verify NDL attribute processing is in useThis is a firmware-level vulnerability in the chip itself - if the affected Qualcomm chip is present and running firmware, NDL attribute processing is handled by the firmware internallyAffected if The device uses one of the affected chip models and is running firmware that has not been patched by the vendor
If your device contains any of the listed Qualcomm chips (Aqt1000, Ar8031, Ar8035, Csr8811, Csra6620, Csra6640, Csrb31024, Ipq5010) and the firmware has not been updated to a vendor-patched version, you are likely affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware patches from Qualcomm and device manufacturers. No workarounds available; affected devices must be updated to patched firmware versions.
