CVE-2023-33069
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 · uneditedMemory corruption in Audio while processing the calibration data returned from ACDB loader.
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 memory corruption vulnerability exists in the Audio component when processing calibration data returned from the ACDB (Audio Calibration Database) loader. The vulnerability allows memory to be corrupted, likely due to improper bounds checking or buffer handling when parsing the calibration data, potentially leading to code execution or 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 chipset or firmware in useLocate the Qualcomm firmware version or chipset model number on the device. This may be found in system information, firmware build details, or device specifications for the modem, connectivity, or audio subsystem components.Affected if The device uses any of the affected Qualcomm components: 9206 LTE Modem, Aqt1000, Ar8035, C V2x 9150, Fastconnect 6200, 6700, 6800, or 6900 firmware.
-
Confirm audio ACDB loader functionality is activeDetermine if the Audio Calibration Database (ACDB) feature is enabled or being used on the device. This typically involves checking if audio driver services related to calibration data loading are running or if audio configuration files are being processed.Affected if The ACDB loader processes calibration data on the device, which is the code path where the memory corruption occurs.
-
Check for vendor firmware or driver patch levelReview the installed firmware version or driver patch level against any available vendor security advisories for CVE-2023-33069. Compare the build date or version string to the patched release.Affected if The installed firmware or audio driver predates the vendor patch for this vulnerability, or no patch has been applied.
The environment is affected if the device runs any version of the listed Qualcomm firmware components and uses the Audio ACDB calibration data processing feature.

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 the vendor-specific patch for this vulnerability. As this is a memory corruption issue in audio calibration data processing, ensure audio driver updates from the affected vendor are applied. No public workarounds are available.
