CVE-2024-21463
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 while processing Codec2 during v13k decoder pitch synthesis.
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 confidenceMemory corruption vulnerability in Codec2's v13k decoder pitch synthesis allows potential remote code execution. The issue occurs during processing of Codec2 audio data, where improper handling of the pitch synthesis operation leads to memory 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 checksWork through these to decide whether this CVE applies to you.
-
Identify Qualcomm component in useInventory your system's hardware and firmware to determine if it contains any Qualcomm components: Ar8035, Fastconnect 6200/6700/6900/7800, or Qam8255p/8295p/8650p. Check device documentation, hardware specs, or system information utilities that list network or wireless adapters.Affected if The system uses any of the listed Qualcomm firmware products.
-
Check firmware version of Qualcomm componentUse the vendor-provided tool or command to query the firmware version of the specific Qualcomm component identified. For Fastconnect adapters, this may be via 'lspci -v', 'iw list', or vendor-specific diagnostic tools. For Qam modules, check via the embedded system's firmware management interface.Affected if The firmware version is any version (all versions are affected per the advisory).
-
Verify Codec2 audio processing is enabledDetermine if the system or application uses Codec2 for audio encoding/decoding. Check configuration files, application settings, or running processes that utilize the Codec2 library for audio operations.Affected if Codec2 audio processing is enabled and the v13k decoder is in use.
-
Confirm v13k decoder is activeInspect active audio pipelines or decode operations to identify if the v13k decoder is being invoked. This may require checking audio daemon logs, debug output, or monitoring active codec instances.Affected if The v13k decoder is actively processing Codec2 audio data.
If the system contains any of the listed Qualcomm firmware products and uses Codec2 audio processing with the v13k decoder, the environment is vulnerable to this CVE.

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 dataUpdate Codec2 library to the latest patched version or apply vendor-specific patches for products using the vulnerable v13k decoder. If no patch is available, consider disabling Codec2 audio processing or implementing input validation guards.
