CVE-2017-18299
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 · uneditedImproper translation table consolidation logic leads to resource exhaustion and QSEE error in Snapdragon Automobile, Snapdragon Mobile and Snapdragon Wear in version MDM9206, MDM9607, MDM9650, MSM8996AU, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 625, SD 650/52, SD 820, SD 820A, SD 835, SD 845, SD 850, SDA660
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 confidenceVulnerability in Qualcomm Snapdragon SoC firmware where improper translation table consolidation logic in the secure execution environment (QSEE) leads to resource exhaustion, causing QSEE errors and potential denial of service in the trusted execution environment.

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 SoC modelCheck /proc/cpuinfo or device system information to determine the exact Qualcomm chipset (Mdm9206, Mdm9607, Mdm9650, Msm8996au, Sd 210, Sd 212, Sd 205, or Sd 450)Affected if The device uses any of the affected chipset models listed in the CVE
-
Verify firmware versionRetrieve the firmware version from the device (typically via /proc/version, AT commands, or manufacturer-specific diagnostic tools)Affected if The device runs on any of the affected chipsets regardless of version since all versions are vulnerable
-
Confirm QSEE is activeCheck system logs (dmesg, logcat) or QSEE-related system files to verify the secure execution environment is present and runningAffected if QSEE is present on the device (all listed chipsets have QSEE)
-
Look for QSEE errorsExamine system logs for QSEE-related error messages, particularly those indicating translation table issues or resource exhaustionAffected if QSEE errors related to translation table consolidation or resource exhaustion are logged
A device is affected if it uses any of the listed Qualcomm chipsets (Mdm9206, Mdm9607, Mdm9650, Msm8996au, Sd 210, Sd 212, Sd 205, or Sd 450) since all firmware versions for these models contain the vulnerability in the QSEE translation table consolidation logic.

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 dataFirmware-level patch required from Qualcomm to correct the translation table consolidation logic in QSEE; device manufacturers must integrate and distribute the updated secure firmware to end users.
